I would love to have a variable dB (6,12,24) per octave on the HPF. Besides that I would wish for a LPF in all PEQ (same with variable dB per octave).
Also variable curves for the shelf’s would be more pro in my view.
Now the shelf’s are very flat.
Also more narrow Bell-EQs would be nice for reducing feeding frequencies. I mean a Q=10 or something
