Re: yet another 'new, shiny' feature that gets a *yawn*
It works better if you realise they missed the log out/log back in the setup help. Didn't check if it applies changed folder lists but it doesn't update your app whitelist without it. Cue much annoyance.
Also if you're using a 'select folder' file dialog it will just silently fail to write. No warning. Be careful.
