Quick (Alpha S5+)

Adds few cool things:

• can change color of wheels in edit panel;
• directories are bold to see them between sound files;
• hold A key and click and drag from a wheel to another to toggle mute state of both wheels in sync;
• hold S key and hold click on a wheel to solo it, revert when release click;
• see wheel name on hover, and fraction on link hover;
• pan the workspace by holding D key and dragging the background.

Plus tiny fixes.
Enjoy
