Created attachment 170924 [details] Screenshot with hidden NB items With Standard Toolbar interface, resize window to about the same size as in the screenshot, and switch to Tabbed UI. => There's quite a lot of empty space, and a large part of the notebookbar isn't shown by default (1st screenshot). After clicking on the arrow on the right twice (to display the rest of the icons, then hide them again), the notebookbar is filled correctly (2nd screenshot). Observed using LO 7.2.0.0.alpha0+ (c088d26578d1be352efa49bd164a8217627648de) / Ubuntu.
