I've done another mock ups that change much more in layouts.
My aim was to:
* make a minimalistic look (so to keep the tendency of Compact Player's recent changes),
* get rid off frames wherever possible (anti-skeumorphic tendencies of Windows 8 Modern/Metro UI)
* save as much workspace as possible. I've managed to reduce the amount of toolbars by sending many of the buttons and tools to the Caption Bar.
(notice that there are two different background clours in library for every other verse, but that;s just the thing herited from the skin:) It should be as plain and of the same colour as background of Right or Left Panel. my graphic skills were to poor to change it:))
they stay the same as in the 1st post, but just paste to refresh the idea:)
