Very nice. One thing that I always find myself wanting when exploring new editors is a way to import my Textmate theme.
It's tough to evaluate the editor when the colors are all wrong, and I don't want to spend the time to set them up just right only to find out I don't like the editor. I think a feature like that could help increase adoption.
.tmTheme files are supported by Sublime Text: Copy your .tmTheme into ~/Library/Application Support/Sublime Text 2/Packages/User (assuming you're on OS X), restart Sublime Text, and you should be able to select it from the Preferences menu.
