This reverts the temporary fix for #5534
(commit 99b6e75956 )
and implements a proper fix.
This also closes#5570 as that was a side-effect of the initial
half-assed fix.
- Revamped the flags ui to be consistent with the rest
- The expand setting is on by default now. Tweaks to its dialog and
header
- Added a new kiosk mode that will use the entire screen for the
workbench
- Got rid of the auto-hiding behaviour of the header which gets annoying
quick
