Enable "Show Tab and Commands All the Time" as a permanent setting in fullscreen mode
This is already possible. Click the 2nd of the 5 buttons in the top right corner and select 'show tabs and commands'.
It should remember this setting when you close and open the program. Still possibly an issue if you exit/enter full screen a lot, as I think you have to reapply the setting. I just stay in full screen all the time.
