I have a few suggestions for new versions of renoise:

1: The ability to mute and solo individual note columns inside of tracks, and maybe even the effect columns (ie be able to turn effect commands on/off)

2: The ability to midi map individual track’s patterns in the pattern matrix for triggering. Also, once the track’s pattern is triggered the ability to have it loop automatically.

3: The ability to midi map any VST’s parameter that can already be automated by envelopes.

You can already mute note columns separately.

Not sure what you mean, you can midi map pattern triggering. Playing different tracks separately from same pattern is not possible, and most likely won’t be in near future. You can mute tracks in the pattern matrix though.

You can do that, you just need to use the #automation device.
