Very nice. There was an older similar app I had used for a while, but it broke on latest OS update. this one looks good. will give it a few days and then buy. thanks. two requests:

1. some windows do not show up in the list, eg: this very app's settings window, when open, does not show up.

2. "group by app" is a bit much, since i like a full window list, but "order by app" would be nice (so all Sublime windows are next to each other in the list), this avoids: "sublime file a, sublime file b, finder, sublime find c" which is messy
