Right click should be the "x" instead of shift and it would great if you could enter pan mode by dragging on the area outside of the puzzle as well. Also hotkeying the color changes or at least a single key to rotate through them
We'll consider the other ideas, but the colour hotkeys already exist (from the instructions):
(2-8) Switches to the corresponding colour.
(Z) Cycles through all available colours as well as the “cross”.
EDIT: Right click is now a "shortcut" for the "X".
