my suggestion : GUI - customizable size !
1) MIXERS : Especially when it comes to mixing (EQs) i really appreciate when every channel can offer (at the top) a slim EQ channel instead of a big plugin you have to open/close. Just like real hardware !!!!! (although additional features can be reachable too)
2) "RACK SPIRIT" : why don't the synth, effects follow the same logic than the 19' rack? I mean if vinco, reverb, synth had the same size (horizontal) within scope that would be easier to organize screen sets... and more pleasant ! It is up to each customer to purchase a good graphic card that allows you to have a sharp image for small elements (which means 120/150€ for such a graphic card...)
