A lot of my files were shitty 480p versions of movies from the Napster days. Now they’re all 1080p, with a few 720p exceptions (mainly tv series episodes). All in all 500 something files in total. Now just watching uTorrent slowly download them all. Hopefully my VPN keeps the eyes off of me…
My own take on it is that it’s, hmm, not really bad design, just unforgiving.
When you see that you’re about to make more than X number of changes, Stop… verify with the user, then move forward.
