What Dev tools/practices would you love to see getting adapted into the normal world?

I would like to fork Spotify playlists!

You should be able to hack around that. Create an empty playlist, select all songs (CTRL+A) in the playlist you want to fork and then drag/drop them in your empty playlist.

Need to use the desktop app though. Also haven't tried it, but I think I did that at one point.

Ctrl + Z

Git in the office. Everything is so slow because people accidentally delete excel files, I fucking hate my school (and probs the govt too) for this.
