546621 - 'Show in conversation' feature is too hidden - add a "Conversation" toolbar button

Status: RESOLVED FIXED

(Thunderbird :: Message Reader UI, enhancement)

Description

[Max Spicer]

Thunderbird 3's new Show In Conversation feature is fantastic.  However, it's too hard to discover.  The feature is buried under 'other actions' in the message view pane.  I've shown this feature to many users who already use Thunderbird 3 yet hadn't discovered it for themselves.  They've been really impressed with it, and many have said they wished they'd known it was there all along.  I would suggest that the UI to this could do with a re-work to make such a good feature more easily discoverable.

There are possibly two issues here.  The first being that the feature is hidden under 'other actions'.  Secondly, it's perhaps not that clear what 'show in conversation' actually means.

Comment 1

[Dan Mosedale (:dmosedale, :dmose)]

I would tend to agree with this, and if it's something that we could address without too much design work, I'd love to see it addressed in the short term.  clarkbw, how much work do you think this is likely to be to address this, and is now the right time?

Comment 2

[Bryan Clark (DevTools PM) [:clarkbw]]

Not sure what the right solution would be here.  I agree it would be great to surface this feature more than it is now but I don't have a clear path to an easy fix so I'm feeling like this might have to sit on the roadmap a little longer until we can get some designs for possible solutions.

Ideas we had about this earlier were to place a section at the end of the message (the end of the scrolled message area) where we can show a link to ( See Entire Conversation )

More ideas (and even just variations) would be greatly appreciated.

Comment 3

[Mark Banner (:standard8)]

How about just including it in the Message Menu and the right-click context menu? 

They are pretty much the locations where until now most people would expect all these things to be (and all other items in "other actions" are available in the standard menus).

Comment 4

[Max Spicer]

I don't think putting this feature in the message menu or context menu would solve the issue of making it more visible.  I think it needs to be something that is visible by default, like for example the reply button, or the other actions menu itself.  I appreciate that real-estate is going to be an issue here, but I think this is such a useful feature that it deserves some space.

I also don't think putting a link at the end of the scrolled message area would work for me, as I find I use the feature most when I'm going back to a message that I've already read.  I'm using the message as a start point to jump me into the conversation, so I don't generally scroll through that message.  Even for new messages it is often still helpful to go to the original conversation before taking in the new details.

How about adding a 'yellow bar' (like the Show Remote Content bar) to the top of messages that are part of a conversation.  An initial implementation could just say 'This message is part of a conversation.  View Conversation'. or similar.

This bar could go on to be used to give more information about a messages context.  For example, for messages that you've replied to it could say, 'You replied to this message on 1/2/2010 at 12:35pm.  [View Conversation]'.  Such feature creep should probably be the subject of another bug, however!

I'm liking View Conversation more than View In Conversation.  In my opinion, 'view in conversation' makes it less clear what the feature does.

Mark, this will be fixed by Bug 525890 as soon as it gets your review - Missing (context) menu: Message > "Show in conversation"

While bug 525890 will help to some extent, I think this bug should stay open to explore other ways of making this more discoverable (Bryan's comment 2).

> Secondly, it's perhaps not that clear what 'show in conversation' actually
> means.

Bug 525890 has changed the caption to "Open in conversation" (proposed by Bryan), as it's pretty much related to "openening" a msg (in its context).
In the same line of thought, we also implemented Ctrl+Shift+O as a keyboard shortcut for "Open in conversation", derived from Ctrl+O for "Open". I don't have strong feelings about the caption, but I think the concept of "Opening" makes a lot of sense and for many people it might just be "the other way of opening a message". "Open" is the established term that we use in the UI to describe the action of "showing" / "viewing" a msg.

Comment 7

[Max Spicer]

I think my problem is that it's not really clear what '*in* conversation' means.  I'd like to suggest 'Open Whole Conversation'.  I think this makes it much clearer what this action will do.  (comment also added to bug 525890).

Whilst I'm commenting here, I'd like to re-iterate that this bug is about far more than a context menu or keyboard shortcut.  These are not easily discoverable features.

Hmm. Not sure. We're /not/ really opening the whole conversation (i.e. every msg. of that conversation), what we actually do is "Open (selected) Message in the context of its conversation". But that's too long for a caption. The short version is "Open Message in conversation".  In the message menu, we skip the word Message, as we expect the user to implicitly read the word message with every command, like this: "Message > Open in conversation" = "Open [Message] in conversation".
I don't think this caption in itself is unclear. Some ambiguity arises when we iuxtapose this with the other "Open" variants:
"Open in new tab"
"Open in new window"
"Open in conversation"
It's confusing because the parallel wording might suggest that "conversation" is structurally similar to "new tab" or "new window". But in fact, you could open a message in conversation in a new window, or a new tab. But we don't offer that yet, we'd probably need different UI with popups for that.

Comment 9

[Steve Mokris]

Perhaps add a preference to make "Open in conversation" the default "Open" behavior?  (This wouldn't help with discoverability, but would help with usability once it is discovered.)

(Oh, just to expand a little on that, I've added a button to the customize dialog of the message header and mail toolbar so that people can more easily access the functionality.

Does this really help, though? I'm ok with this, since I don't know if it should be in the primary UI all the time (I only rarely use this option, much less often than any of the other header buttons*), but I'm not sure how you'd make it more discoverable otherwise.

We should also hook up all the other "show in conversation" commands to this new <command> node to facilitate code reuse**. This would be a good time to fix bug 550775, too.

* To be fair, I might use it more if conversations weren't broken on Gmail due to how Gmail structures its folders.
** It would also get us one small step closer to using command="" instead of oncommand="" for our buttons/menu-items, which will make the "menu and toolbar usage" Test Pilot study much easier to implement.

Comment 13

[Andreas Nilsson (:andreasn)]

Attachment: icon proposals

A couple of icon variants I've came up with.
From left to right:
1. Same as thread icon
2. Breaking out thread
3. Well established metaphor on cell phone UIs
4. I think we want to save this one for a future generic-in-tab-menu feature.

Comment 14

[Blake Winton (:bwinton) (:☕️)]

How about something along the lines of a chat bubble?

(#2 seems a little too much like a flag to me.
 #3 seems more like "Send and Receive" than "Open in conversation".)

Comment 15

[Andreas Nilsson (:andreasn)]

Chat bubble have been on my mind, but then there is also bug #714733

Comment 16

[Blake Winton (:bwinton) (:☕️)]

Yeah, that was my concern, too.  On the other hand, we may open chat results in that tab, too, so it might fit…  ;)

And we could still use a silhouetted head for "chat with this user"…

When multiple messages are selected, only the first opens in conversation tab.
Should this part be removed from messageWindow.js?

My changing of the reviewer didn't subscribe me to the bug, grrr.

Found it. But the menu item doesn't show on the topmost message in the folder, strange. I'll try the patch now.

(In reply to Magnus Melin from comment #30)
> You enable it by enabling gloda. (I have it disabled too...)
I have that enabled, as Kent says: We need to eat our own dog food. Did you know that Gloda autocomplete is completely broken? Bug 1271445 comment #11.

Comment 34

[Jorg K (CEST = GMT+2)]

Can someone please explain to me when the various "Open in Conversation" menu items/buttons should be enabled/present. Does that only work when Gloda has index them?

If I select two messages each of which has "Open in Conversation", both of them selected results in
Message > "Open in Conversation" greyed out. However, the new button stays enabled. So there is something wrong here. As Richard pointed out, if you select two messages from different threads, only one in displayed in a conversation. So I'd recommend that the button follow the menu item and get disabled when more than one message is selected.

[Magnus Melin [:mkmelin]]

Yes, that's why I'd keep it enabled only when one message is selected.

Would be pretty sweat to use it from the standalone message window, but if it doesn't work you should remove it.

I removed it because it doesn't work in standalone message window because it can't find a tab. This could surely been fixed but is not in my capabilities. Also the conversation menuitem in this window is alwasy disabled

Sorry, this is correct in a way, but I realized we already have cmd_openConversation, so you should just put the button_showconversation case next to that and fall through, for all the cases

for controllers you have three cases: supported, enabled and docommand. 

you just have two cases, so supports/or enabled is missing. (I don't see which in the diff)

The case "button_showconversation": is in supportsCommand: function(command) and isCommandEnabled: function(command)

In doCommand: function(command, aTab) it's missing. Do I need to add here something like:

case "button_showconversation":
  break;
