This is probably off-topic, but probably not worth a separate post, so I didn't know what to do: speaking of cleared, it would be lovely to have the choice of "transparent" for the background and foreground colors. I end up going out of KM to create icons because I often want them to have transparent foregrounds or backgrounds. (Well, normally backgrounds anyway.) This is so the background doesn't show up in the icons when the macros are on a palette.
(My transparent icon is vaguely relevant here.)
