The new beta looks good. Haven't had time to test it much, but I'm pretty happy about a lot of the fixes (like the improved bracket auto-matching behavior).
Two minor annoyances:
Firstly, I'd expect shifting lines by using ctrl+shift+up/down to automatically adjust their indentation. This is pretty standard in a lot of editors.
Secondly, the way I select a lot of lines usually involves going to the first character on the first line, then doing shift+down until I get to the line I want.
This causes a problem every time I copy paste lines, since Sublime assumes I want all the other lines indented more than the first line.
This is how I've selected text for years, and I'm pretty sure many others also do this, so this might be something we'd like to fix (although I'm not sure what a fix would look like, actually). I think other editors also support this, since I've never had this problem before, but it might be smart to check how e.g. Eclipse handles this.
