Make a "Master" Track. Set it to record from master out l/r, rec enable
and press play/record. Wait for session to be recorded. look at master
peak file for level issues, adjust levels, re-record...
These steps could be automated and made a preference. There is also room
to make this dynamic and less demanding of disk space by only generating
a peak file and not the whole wave file aswell.

It's very useful as a mixing environment. IMO it's the best open source
environment for mixing tracks/sessions/sound tracks.

Some time spent on this feature will save a lot of people a lot of time
in the future.
