I agree there is some correlation with "
mystery meat" website navigation, but there is a world of difference in the scale.
MMN is a sin because all the designer had to do was write "Home, News, About, FAQ, Contact" and they were good to go. In the case of Live it is a much more complex beast. It really does have a hell of a lot of functions and they have to go somewhere, and as you say "a button for everything" wouldn't work.
So it shares some problems with MMN, but it is a whole order of scale different and that is why it is so hard to solve properly.
Perhaps there are some users who want to throw away a load of functionality to make the app simpler, but for each user the "functions I don't use" set is different and different each day.
It's a hard, hard problem to solve. The app needs the complexity, the various functions, but every day it becomes like writing a new episode of the Star Trek franchise, around every corner is a different shaped fanboy chastising the author for neglecting some arcane item. The wriggle room gets smaller each iteration.
I find it hard to come up with a solution myself, so I can't criticise anyone else for failing to find an amazing innovative solution!
Nobody seems to want Live split into two products, so my best suggestion is a modular load, similar to an #include method
Angstrom: load mode:My Stage Template
#include Session
#include Mixer
Angstrom: load mode: My Studio Template
#include Session
#include Mixer
#include Arrangement
#include Arrangement Mixer
#include Folder Tracks
etc
In fact I'm going to put a wish in for that, just for a laugh
