The whole idea of this is to have what's been asked for already, a multi picker that is always on top and you don't have to go in and out of picker windows then not be able to access Baib while in the jail window.
If you could type a RealTrack number in the Mixer it would speed things up.
The "RD3" picker (that you type in the chord sheet) is very slow and also shows the current Drum in the list that stuffs thing up with AHK (see pic below), the RT3 is pretty good, if you could leave it open like the Alt+F8 Regenerate Part window that is not a Jail, you could have a multi tab floating Picker for direct access without having to go in and out of pickers.
You could have Style, RealTracks, RealDrums, Midi Super Tracks, Midi tracks, UserTracks (with Holds) and loops all in the one picker.

If Biab had scripting it can be all done in a short time without having to wait yet another year to maybe get it.
The one above took a few days to make not a few years.
