The "Cut Page" has been a godsend for me. I'm going through about 1500 hours of footage right now and that editing mode is the only thing that has made my task even remotely possible for me to pull off.
I don't know if you ever played FPSes in the early days of Quake, Doom, etc. but remember how you used to just play with a keyboard and it was okay, but then you switched to mouselook and it was just a whole 'nother world?
That's what the Speed Editor does.
