Bump. +1
I have setups 3+1 monitors (3 for editing, 1 for preview) and 6 monitors (2 rows of 3). And DaVinci is unusable with current unmodifiable UI.
It is not even remembers window size/position if I change it's starting size from only 1 monitor to take whole space I need.
Trying to migrate from APP for a week and thinking about buying a Studio plus Editor Keyboard but... such things stops me. Most of of the Davinci current UI is a waste of space. And I can't do anything. This UI was designed IMHO for 16:9 onlyr one or two "DualScreen" monitors. Very sad. Some features are the best at the market, but...
Just for compare (3+1 setup):
