I would love to see an input meter and trim knob for each buss master (aux, group, fx, etc).
Input Meter - This is especially important when troubleshooting and wanting to confirm input levels. Because of inserts and processing on the strip, the output meter is not the same. It is weird to see all the meters at the top of the strip with no signal because they are for Ext In, which I rarely if ever use - maybe those could be a smaller meter to the side, or swapped out with a preference? I would love to see the input meter added to the processing tab as well, in addition to the “Ext In” that is already there.
Trim - modify levels coming into the buss master - this is particularly helpful if you want to hit a compressor/limiter harder coming into the strip.
