Thanks a lot, Lyndel!
So PEP looks for a matching function name - that would work, I guess.
As I said, until now, I'm using "single action macros" with the delay for a specific device, e.g. "AVR Startup Time", and insert those into all action lists after calling the corresponding power on function.
I think none of my older Pronto models had a configurable power on delay for devices.

Anyway, I'll give it a try. I'm not using any animations so far, so that shouldn't be an issue.

Regarding the general delay - I was under the impression, that this is applied, well, generally.
I.e. not only in between digits, but all buttons.
Of course, the effects of a wrong value would most likely be seen in channel macros.

BTW, instead of renaming all your functions, you could have simply set the delay values to zero - or not? ;)
