So I did look into multichannel support but... the way Reaper handles sends/receives with extra channels is (IMO) really weird and I can't figure it out. So that's not happening.

I don't have time to actually test this, but try replacing lines 49 through 73 with:

-- Loop through all tracks in the project
for i = 1, reaper.CountSelectedTracks(0) - 1 do
	
	_=dm and Msg("looking at track "..i)
	
	local tr = reaper.GetSelectedTrack(0, i)
	
	_=dm and Msg("\tdepth = "..reaper.GetTrackDepth(tr))
	_=dm and Msg("\tp_send = "..tostring( reaper.GetMediaTrackInfo_Value(tr, "B_MAINSEND") ) )
	
	_=dm and Msg("\trerouting")
	
	-- Disable Master Out
	reaper.SetMediaTrackInfo_Value(tr, "B_MAINSEND", 0)
		
	-- Add a post-fader send to idx 1
	reaper.CreateTrackSend(tr, bus)
	
end

There's also a feature provided by the SWS extension called "Cue Buss Generator" that does something similar, I think.

Definitely. I prefer to only use folders for things that I might want to hide, just to keep the project less cluttered.
