I just started using sublime text, and I love the ability to quickly open files by pressing ctrl+p and typing in an auto complete text field. So fast! Mac os also has this with the spotlight feature. Here’s a version I wrote for Maya using PyQt. Just press ctrl+p and start typing. It will search a cached index of your project directory for all .ma/.mb files and auto complete. It prioritizes files that you open more often. It also detects files with versioning and puts the latest version on top. I use a QSplashScreen with a little transparency which I fit to the Maya main window to create a sexy overlay.
