Strangely enough pressing play to undo recording has not bothered me.
But I must admit that I sometimes miss a more general undo. There are things that you can do accidently that can mess up your stuff pretty badly. You could argue though, that undo is for sissies:laugh:
Seriously, I think it would be damn nice to be able to undo your latest action. E.g today I accidently hit track RMX, and I just had to live with the result:S
So, *if* we at some time get a general undo command, this could also work as undo recording.
