Ok, confirmed the new build has binaries, and popup text appears to be working. I really do love this new automated build system!
Cabbage is creating a popup for all buttons now, even ones that don't have a string set for the popuptext.
Most other widget types default to the channel name and value if no text is set... but I don't think that makes much sense here, plus it changes gui behavior in a pretty significant way for existing instruments/effects.
I think it would make sense for buttons with no popuptext set to not have any popup. What do you think?
Going further down the rabbit hole... I'm guessing popup prefix and postfix don't make a lot of sense to implement here either.
