Hi BlackInk-Team,
my suggestion is about a general thing. The layer are on the left side (at the moment) and when i´m trying to change the layereffects, my right hand (drawing-hand) is hide the screen^^. So maybe the layereditor could be also on the right side in the Head-up-Display ...and maybe the left-handed guys could mirror the HUD-layout through the preferences in a future update, that would be awesome. Only an idea...hehe...like your interface so far.
