I use Pipeline XT a lot. One thing that drives me nuts is having to look back and forth across the plugin to view the input and output meters. Cut you also substitue the meters with bar meters with peak and RMS? The LED peak meter emulation doesn't give me enough information and I take a lot longer to calibrate the hardware. Those two changes would make using Pipeline a lot easier and really speed up the calibration process.
Thanks for the awesome DAW.
