I finally went in and figured out my problem (and switched my vote from “Broken” to “Working”). You were right on with the problem, btw – I didn’t have categories defined. Since I didn’t see what I needed to do within the first few minutes and didn’t have time at that moment to investigate further, I posted here and put it on the back burner.
I don’t know if you’re looking for advice, but for your next version I’d suggest putting instructions right on your setting page, and possibly changing the text on the Pages view from “Content Status” to “Content Status (Categories)”, which would visually cue the user to the fact that this is something that needs to be changed in the page view itself.
All this being said, now that I’ve figured out my issues, this should be a very helpful tool. ??
