What I love about ST2 is that although it's very data-driven in configuration (several hierarchies of plain text configuration files + a simple python API), it somehow doesn't seem overwhelming, or that I'm missing all the cool tricks. I hope the author continues to comment all the configuration files and will document 100% of the API.

The editor itself has a great fluid feel. Looks-wise, the default theme is nice, and "Soda Dark", which seems to be a community favourite, is gorgeous.
