I would like to see a function in the multitrack editor along the lines of "render selected tracks and time to new track, including fx tails"
It would allow the user to select a time range and tracks. The user could then render a submix from that selection to a new track with fx tails included. So the rendered clip will most likely be longer than the time selection to allow for the fx to finish.
This would be very useful for pulling small segments out of continuous recordings.
It would be an additional option to the functions already available on the right click menu under "Bounce to new track" - but like "Selected Audio Clips in Selected range allowing for FX tails to complete"
