1.) Vim bindings (less impressive accomplishment but necessary for me); 2.) fuzzy matching for files, commands, and settings (this concept really wins); 3.) having a browser as a tab(!, it makes working full screen a joy); 4.) object eval(!); 5.) and EXCELLENT autocomplete -- even in Coffeescript -- most likely a product of the eval stuff going on, but better than Sublime. Wow. GREAT WORK.
My wishlist of generic "power user" features: macros support (for ex., I'd like to set Cmd-Del to delete up one line), configurable margins, more preloaded skins, a way to easily change the color palette of a skin, and tmux / real-time collaboration equivalent.
I have gotten around certain quirks ~ add a tabset to simulate margins, also add a key binding for adding a tabset to mock the vsplit vim command
After the Nifty Minidrive failure and others, I can surely say this is the best money I've spent on Kickstarter.
