First Package. Customizing Undo?


Hi. I started with Atom yesterday. Really liking it so far. Love that packages are JS and debuggable via chrome dev tools. Considering writing a package that makes cmd+z operate like cmd+u if the last action in history was a selection, else like normal cmd+z if not. If one exists, fantastic. If not, that seems like a simple first package to get my feet wet with. Any recommendations on example packages to reference would rock.
