Make Record+Play record for one loop
Record+Play already allows to start recording at the same instant that playback is started, and - when already recording - will stop recording in time with the end of the current loop.
However, when playback has already been started, Record+Play will just stop playback, which is not useful.
Suggestion
Record+Play starts recording at the next start of the loop if playback is already active.
Or
Record+Play start recording for one loop if playback is already active.
Benefit
This would make recording more useful for live performances and easier to use for looping of external instruments.
Potential additions
One additional feature could be to set the number of loops until recording starts/ends with the select knob, like you can set the number of loops to song-load when loading a song during playback.
Both suggestions can make equal sense, so having a setting to switch between them would be cool.
