WIP: Add expert setting for compact bottom bar
In action: (ignore the white dot in the middle :P)
Note, it's not slow, not sure why the video looks like that, I had to lower fps to 15 to be <10Mb
Also, I might need to disable this when expert mode is disabled, ATM it stays on.
I've used French since it was reported as having this issue, but other languages could benefit.
FYI, that's my device default sizes (fonts/UI), and they look horribly huge IRL.
