Alright, I can dig it. However, after creating a Local Project, where does it save those files? When the dialog box for creation pops up and you give it a path, it fetches from the server and pre-populates the 'default' branch from the server. Nothing in the UI changes to show you that you are in a local working branch, not the server default. I think that this is what was confusing to me.
I was working in a local branch from poking around in the IDE, closed the files (without synching as I didn't realize that I was local), and now cannot find them anywhere.
I cannot find any of the work in the documents directory I thought I was locally working in, nor is anything written in the ~/.atom/packages/screeps-ide/.branches tree.
It's a great alpha to a cool IDE approach to things. Excited to see it develop.
