Wow, this is seriously nice. Never heard of it before. Just today I've been trying out Netbeans as I'm a vim addict but my colleagues keep telling me how wonderful their IDEs are - Netbeans was much too heavyweight for my liking, but this looks like just the right balance between features and simplicity/speed.
Loving the mini-map and package manager particularly. The vim emulation seems to cover most of the key ones I use too. Nice work!
