Just tested the new build, great work getting that out.
No fix on the RGB parade invidivual window resizing. I've attached some (rough) screenshots to help understand what has changed and what we should be able to do to maximize the size of the windows on screen.
Ideally, each window would be able to be opened on in their own window and resized separately. so you could potentially have 3 windows on screen one on the left size stretched vertically, and two on the right stacked.
