1) Wouldn't it be great if you could load an entire set of files into a playlist-like menu, lets say to mix an album or a bunch of songs down, and Sonar would just crunch those numbers all by itself? The mixes could be saved to a folder as part of the process, ready for mastering.
2) On the topic of saving time, unless I'm doing something wrong in 7PE, you can't select several tracks or virtual instruments simultanuously for freezing either.
