It would be very nice not to have to open the channel and then the dynamics tab just to see if/how well the compressor is working. I know that you can expand the the channel strip without opening the channel. But then you have to use the cursor to adjust the window, so you can see the meter,which is even more cumbersome.
Without the visual feed back, you might even forget that you have a channel dynamic running! It would nice to just be able to look at the channel (like on the Harrison Mix Bus) and see the volume meter going up and the compressor meter going down.
