Audio editing in Final Cut Pro. Those pink dots and rubber bands drive me crazy, especially if you have to move them. This is not so much a feature as a technique that I started using on the Media100 and works great in Final Cut Pro too.
Actually some editors don't like the fact that Auto Save kicks in when you are about to do something but in fact it may be a real blessing that its been bugging you ever 30 minutes (or so) if you crash in the middle of a big project and you have not developed the "Save All Twitch". (Command-Option-S)
I worked all afternoon an FCP tutorial about audio crossfades and while its processing, I thought I'd link to this video, another cool longboard video. Basically these are long form commercials and frankly, they are working. I'm seriously shopping for a longboard. Not that I'll be able to ride like these kids.
