Better graphical design
Please look at Coda 2. http://panic.com/coda/ / Texmate / Xcode / ...
While there's a low chance that based on current look of Sublime it will be of any importance, I think there's strong evidence that design, look and feel of the app is an important selling point (money).
I've bought Sublime an hour ago in hopes it will get better. I stopped using it (the trial) numerous times because of this before.
I'd like to suggest hiring a better designer to get the design of Sublime on par with some of the better code editing tools out there.
And maybe ditch the "Text" from the title.
