If you make a mistake when recording you should be able to hit the record button again to re-start the recording.
(rather than having to press stop, delete the recording and then start the recording again)
You can set up a macro to do this but it would be nice to be able to do this by hitting the record button again.
A little thing but would really improve workflow.
Being able to capture the last thing you were playing when not in recording would also be nice
