This idea might be tricky, but would be so cool to have a function where you could select two shots and flop the order in the timeline while retaining the same in/out/duration. Have no idea if this is even possible, but would be really cool.
Also, the function could just be limited to 2 clips at a time. Otherwise, you'd probably have to make a dialog box asking what order multiple clips would need to go in, and for that, you'd probably have to show thumbnails of each clip...hmmm might not be a bad idea though...
