In the waveform editor, it would be great to be able to select multiple places of a file, mark them as let's say channel 1, and be able to effect them (amplify, de-reverb,de-noise, etc.) without having to go to each selection again. This way, if you need to go back and tweak one person out of five in the track, you can select all their parts and be able to go back and adjust more easily as opposed to finding all the parts again and tweaking on a more individual basis.
