How would this work on 2 or 3 monitors. Asking this, since any serious content creator tool end up using windows across monitors, and there you need good docking support.

Qt has some, but not all the way there, like Visual Studio has (but there are some good alternatives for Qt).

The other two pain points (for DCC): - HDR support (again across monitors) - Hi-DPI support (and again across monitors)

Once you start hitting issues above (among many small others), you realize how much there is to add (wacom tablet support? What next?)
