Make IOBox (Color) (and every other IOBox that might exhibit this behavior) accept digits separated by ‘,’ (colon) instead of just ‘.’ (dot). IOBox (Value Advanced) and Herr Inspektor already do that, and it’s getting annoying to travel those extra centimeters from the numpad just for that arrogant little colorbox ;)
when duplicating some nodes - keeping the incoming the connections from nodes that were not duplicated.
deleting a link (rightclicking) requires one click less than reconnecting.
saves some time (and nerves) scrolling through crowded patches
