First off, I'm impressed with how well (and quickly!) this is coming along. I've a pair of questions, though:
1) I'd love to be able to quickly create a new file in the current folder; is there an appropriate forum to request features?
2) Quicksilver (MacOS) does, I think, default to using the ctrl-space binding you've selected for autocomplete. I've used the system keyboard preferences to move the autocomplete to a different key combo, but I thought you might want to make this choice configurable.
Solid work, and impressively stable for an alpha product, mate!
