Sublime Text 2 is a text editor for OS X, Linux and Windows, currently in beta.

RegEx search should support lookaround.
Foo(?>Bar)
should (and does) find instances of 'Foo' immediately followed by 'Bar' in my document. But if it were truly lookaround-aware, it would only select 'Foo' as the "search result", instead of 'FooBar'.

Ctrl+9 should select last tab
This would imitate behavior in Firefox and Chrome.

Selective Editing ala KEdit (REXX)
Please, Please PLEASE add selective editing as in KEdit (REXX). Your editor will blow all others away if you add this so it's not clumsy--no others do.
KEdit is unfortunately no longer maintained.
Please? See I asked nice!

I want a preference to prevent me from editing read-only files

More control over mouse bindings

On a mac, build 2036, when I save a new file it assumes a .txt extension and asks if I'm sure I want to use a file extension that's not .txt

Also, when I type in Cmd + A for the file name, I get an audible bell warning.

Highlight the contents of the html style attribute like it was css code.
Right now it displays as a plain string. The Komodo Editor has this feature and I always found it nice.

Separate build/run actions

Find in files: option to not warn about "Unable to open file".
I have a project with a lot of broken symlinks that I can't really do anything about, so most of my "find in files" searches have a few dozen garbage lines that I can't really get rid of. It would be great if there was an option to turn these warnings off.
