A color change on a selected clip portion creates a separation and an equivalent clip. This feature accelerates the work.
Menu item Edit - Separate Clip - At memory location
should be usefull sometime
Have a feature in the Memory location window to put a clip separation everywhere there is a memory location marker for a highlighted track.
For those of us who edit LOTS of voiceovers, I will make separations at all the memory locations (bad parts in the script) so that when I'm editing....I don't move all the audio further down stream, causing it to be off it's marker.
