It seems like openPreviousFiles only really works if you didn't open a file from the shell. If I open the app, it works fine. But right click a file in the shell and open it in the editor and none of the previous files show up. This is proving to be very frustrating. If this is an intentional behavior, I beseech you to alter it. It's totally not what I expect to happen.
That said, it's about damn time someone made a decent editor for Windows. Thanks!
