Sometimes I thinkhow is possible thanRenoiseTeam does not go crazy with so many suggestions from people.
I can only speak for myself, but I started to categorize ideas & suggestions a while back.
And I update the topic whenever features are actually implemented - 3.1 and Redux are looking quite good in this regard:

I should mention that one solution for the column mess is, of course, to record into different tracks. But setting up your midi controller to do that everytime you want to record something is quite something. It would be great to be able to have a template for that or so. So that you can switch between “record into current track” and “record into this specific configuration” with a single toggle, for every connected midi controller.
Yes, in Renoise, instruments are bound to the MIDI controller - not the other way around. So if you load an instrument, it might specify a certain input. That’s cool, but it leaves room for the opposite approach:
This tool (which is 2.8 only, AFAIK) examined that type of workflow:

Would be interesting to revisit that idea, not as much for voice-doubling (although cool), but more for a quick overview and managing “performance templates”, like you point out.
