A couple nitpicks...
* There doesn't seem to be a way to set the file encoding... can I assume that files will always be saved in UTF8 w/o BOM? * There doesn't seem to be a way to set line endings... can I assume that files will always be saved with unix (lf) line endings? By extension, will this fix windows line endings, or mixed to LF line endings? * It would be really nice if there was an integrated command prompt, similar to cloud9's, that could be shown/hidden. Configurable to use a given shell (in windows, I'd prefer a git-bash prompt).
All in all, really nice work, and this may well replace sublimetext everywhere for me. I don't use any of the more advanced plugins with sublime, and I actually like the VSC editor's UI more. They seem to have burrowed the hotkeys from sublimetext.
