Hi, I just got an update to Thunderbird 115.0.1 under Linux.
First, I was missing the window title bar, but luckily I found a setting to restore the regular window title bar and move the search widget out of it. My wish: Please do not mess with this! The current Microsoft Teams and Office examples are good examples on how NOT to do a UI in this regard.
Second, I find no way to fix the order of bars. This is how they look right now:
On the left I wrote down the order in which I expect them to be. The closer to the top, the more general they should be. So, please move the one changing with the switching between mail/addressbook/calendar/... down to the specific section.
Regards,
Andreas
