1. I just tested without the apply upon window close and without it the settings don't get saved. this is, I *think*, because of settings.delay() on line 37. The problem I'm trying to solve is that without this delay() call every update to the username while in the prefs panel kicks off an http request to the API, which is excessive. So the idea is to delay updating the settings until the window is closed, leading to just one API call. Perhaps there's a better way to do what I'm trying to do? 2. I'll add this in the next upload!

I've thought about #1 some more and I think I've got an improvement that will work better. I'll upload a new version when I've got it working.

You mean line 50 `prefs.js` cannot catch the text change and save it immediately to the settings?
