soens, I really like your proposal. The only comment is that substituting Mains (shorter) for Hardware Outputs might be confusing but I like it.

Along with this I would like to see better use of the space above the Audio interface outs.
Like perhaps a phase or correlation meter's, longer mains or other metering choice, K weighting, true dBFS etc.
Wookiee, I like that idea too. I'm always looking for metering plugin options mainly for the Master Output, but I've started using a dead end bus to provide easy setup of metering options for the schOPE and other metering. Having metering on the hardware outputs would be nice, and placing the metering in that blank space on the hardware outputs would be handy, though maybe a little awkward since the outputs are set up in the hardware interface control panel. I leave my Monitor Station metering set to +18 dBu because my audio interfaces have outputs that exceed the next lower option of +10 dBu.
Along those same lines, it would be nice if offsets could be entered to display dBu and dB spl. The offsets would be somewhat arbitrary, but I try to use my Monitor Station metering and Radio Shack spl meter to keep all this in perspective, but being able to setup metering with the correct scales and with scale factors based on actual measurements would be helpful, I think.
