What about a full Screen Edit Mode!?
I really liked this feature in FT2 or Digitracker.
r e n o i s e - wahuuu!!! 
plus, by clicking the button on the right, you can enter full-screen mode, i.e: the application will occupy the entire screen, just like FT2 did
Oh yes. thx Bantai!
My fault.
But a single key assignment for faster collapsing
the top and bottom frame would be perfect.
Hit F5 (F1-F7 are the global view presets) to do so.
