It would be nice if there were a size slider for icons in the control panel. Or at least three size options in the context menu.

I use a midi keyboard, so it would also be nice if icons could snap to a half grid space so it would be a little easier to lay things out like a keyboard.

Also, it would be nice if icons in the control panel would take the same color as the labels in the triggers panel. Or at least be able to assign colors to icons individually or in groups.

Also, it would be REALLY nice if the "remove trigger key" and "remove midi note" options worked on an entire selection. Sometimes I want to remove all of the trigger from the control panel, or some group of icons, and it's a real pain to remove them individually. Sometimes it's just nice to start with a clean slate.

It could also be nice to have a set of generic artwork that could be used for random things. Or just being able to assign a couple letters or numbers or the trigger name so it's easier to keep track of triggers without having to link the artwork.
