I know i was using buttons as layer selectors in Swarm, but i could attach them to LayerMem.
Is it possible to make your own LayerMem, or to attach buttons to layer selection if there's no LayerMem present?
I'm trying to make layer selector in two rows, and right now i have a clunky solution (two layer selectors for the same pane one covering 1-4 and one 5-8 and "clipped" by a pane.
