• The design looks quite a bit different than Matt Miklic's card-based design. Was that design dropped?
• This is missing the media settings that existed in the previous version - safe to assume these will be added in a separate PR also targeted for v4.4?
• The Undo button in the toolbar seems really out of place, especially when the screen is first shown and the user hasn't even changed anything. My vote would be to drop undo entirely - it doesn't seem necessary, and I don't think I've seen Undo in any app's settings before.
• I get a "Fragment SiteSettingsFragment{3db9ed66} not attached to Activity" IllegalStateException if I rotate the device while site settings is showing.
• I get a toast saying, "Error getting site info" whenever I try to view the settings for my self-hosted blog (looks like an auth error). When that happens, I'm left with a screen that has nothing filled in, and backing out results in a crash (NPE in SiteSettingsFragment.generatePostParams). Video demo here.
• I can repro the above problem by putting the device in airplane mode and opening site settings. If I enable airplane mode after site settings is displayed, I can edit the site title, tagline, etc., and it acts as though the changes have been saved even though they haven't.

Yes! Thank you for the reminder, I'll open a ticket for it.

I'll be shuffling the design up in the next two PRs (coming soon) to keep it in line with the discussion. I decided to submit with what Android gives us based on @roundhill's feedback: Sounds like a good idea to me, just keep it native using whatever PreferenceFragment provides. I’m doing something similar for the new notifications control center.

Re-opening to merge into different branch.
