install 78.1 or 78.2
there is no calendar. There is no mainmenu item for calendar (after activating menu). There was for 68, wasn't there?
After clicking around, I found the icon that activates calendar. I am not sure that icon (tiny) is really self explaining if one searches for calendar.
After clicking, the page tells that a (one) calendar needs to be activated. Also, there is a greyed out private calendar. (why would it be greyed out/inactive when a user deliberately activates the calendars? That is unintuitive. The user has already expressed that he/she wants to use calendar).
For a new user: how the hell do I activate a calendar?
For old users: there is a hunch to right click the disabled calendar to verify what can be done there. But even here, activation is hidden under properties.
How do we expect new users to find that?
is should be easy to find and activate calendar, however the UI engineers choose to do it. It should be possible without guessing, clicking around and trying out context menues and submenu items without guidance.
When I installed TB and clicked away the setup email account, there was a page for setting up everything. Anyway, after setting up an email account with the inital dialog, that page is gone and I have no idea how to get back there.
As overall observation, I found that easier in 68
