> Open a message by double-clicking it so that it appears in a new window / tab.

For me double-clicking opens a new tab, not a window. Also, when I have the message open in the new tab I **don't** see a "tag" button. There is only a "more" button and inside it there is a "tag" selection and setting a tag there works OK for me.

However, if I right click the message and open it in a new window, I then see the "tag" button to the right of "Get messages" and "Write" buttons. But setting the tag there also works for me.

I haven't tried booting into windows to see if maybe this is OS dependent.

Ok, I tried one more thing on linux. I added a custom "Tag" toolbar button item which shows up along the top row of the display by itself. It  works OK when message in preview pane but **doesn't work** when in a tab. I also see a message in error log like is reported in comment 0:
```
13:38:46.216
An error occurred executing the cmd_toggleTag command: TypeError: can't 
access property "target", event is undefined
globalOverlay.js:102:13
```
I don't see any mention of "custom" or "toolbar" in above comments so I'll assume the reporters have added the custom button or windows includes it by default and linux doesn't.

~~For me double-clicking opens a new tab, not a window.~~ (Edit: N/A -- it's a config option.) Also, when I have the message open in the new tab I **don't** see a "tag" button. There is only a "more" button and inside it there is a "tag" selection and setting a tag there works OK for me.
