"Allowing/requiring users to design their own GUI"

That's why Reaper was invented, more user control, no nanny and father xmas feeding the chickens at the end of the year.

"I think this is a bad idea! Just placing a GUI bandaid over the existing GUI does NOT help!"
Leave it the win98 color and get onto every other DAW company that has a better looking color gui and ask them wt# are they doing.

As said before I'll just go to Reaper that gives just about total control to the user over just about everything and spend my time creating a script to import sections of recorded wav files that users upload n share with the chord markers in them with BWF bext chunk and acid info.
I think that will be a lot easier and very much appreciated in the Reaper forum.

Sorry it's just way too low, back in a DOS time warp that is perpetuated.

It is where it is because of the very statement below,

bye 1995 hello 2016.
