I personally support the idea of layers (such a cycling pattern on layer 1 and a ripple effect on layer 2) for both lighting and actions. It's pretty difficult to organize the effects at the moment. If you consider lighting effects I haven't found a way to "manage" them at all - all i can do is clear it completely.
Some more features I'd like to see:
-Idle mode lighting (without 3rd party software). Although after playing around a bit you can probably set it up with timer and keystrokes a default option would be nicer.
-Action driven lighting for specific groups to setup let's say a key press triggering an effect in specific group of keys (rather than whole keyboard).
-Key groups for assignment menu (setting up actions key by key is not fun)
-Chain lighting effect (i.e. end if 1 lighting effect triggering another) or a cycle action that doesn't have to be triggered.
-Edit: Keystrokes with ANY keys. I wanted to record Ctrl+Shift+Lighting button (on keyboard). Ctrl,shift and alt are invisible (to CUE) as single keys and lighting button seems to be invisible at all items.
-Edit2: Multiple actions on 1 key (or again layering) or ability for 1 action to trigger more than 1 action.
