My proposal:
4398 
Renoise branding has been removed (as if we don’t know it’s Renoise by now…)
BPM, LPB and other non esential data has been moved to the “META” tab. This can be a catch all for non essential info such as Song Title, Description. Or in a theoretical future for something like an UNDO HISTORY Interface.
Status messages are “floating”
PS: Bonus Linux WM decorators bug…
(Tabs should be flipped [most important to the right], floating message should not be ugly, i suck at Gimp, etc)
