Is there a limit to the number of leader keys you can define? I was experimenting with it a while back, but everything after LEAD(7) is ignored. I tried changing the subroutine for LEAD(8) to a lower number and it executes fine.
Does it make any difference when the plugin is loaded?
My sketch uses 18% of storage & 22% dynamic memory. Ideally it would have at least 13 leader keys.
