I would like to second DSM here. I'm streaming more now than recording nowdays. This is the trend since YT is screwing the motivation out of the little guys.
Also be able to adjust volumes without a restart would be nice too
They are not the only ones, I'm in the same boat after recording much of the day now experiencing the same problems. Recordings failing to finalize, then force close Action! to see it reopen on itself.
Quite disappointing as I have been using the program with little issue till now
