Using Chrome on the mac, the "New Project" shortcut open a private browsing window. I believe the browser shortcut issues are being addressed already though.
Overall I like the idea a lot, I've just began learning how to use VIM and this app seems a nice way to learn, but as has already been mentioned it seems more like a practise tool rather than actual teaching. The only way to learn the answer is by getting it wrong the first time. I think there needs to be more focus on the "shortcuts" tab, or at least integrate together with the main app.
