Ooh my lord, as I am typing I just think: you know what would be a real dream? If you could select any region in the destination you've edited ever before, and recall the exact location in the source where you got that edit from back when you made it, so you can immediately change it, fix it or whatever! I don't beleve Sequoia and Pyramix even have that! Well, that's got to be stuff for the far future, but it would definitely make Reaper THE DAW to use for classical projects.
