I've been using it since the first alpha release back in December or whenever it was released and I can say that alpha absolutely fixes the one character at a time undo (and has since the first release).

I actually do like TM's undo. I've found traditional undo mechanisms undo too much when working in code.

> TM had a lot of fans, but no-one liked its undo

What an absurd generalization.

That's actually one of the things I miss most when using other editors. Most seem to undo a bit too much.
