Demian, the planned functionalities for 2.6 sound really awesome. I am intrigued though with the approach for the Setting UI getting split into separate UI.
In my case, I have two 24 inch monitors, and it is common to have multiple programs running at the same time, usually SketchUp, Enscape, Photoshop and MS Outlook, plus any Window Explorer windows with project directory files showing so I may track the work I am doing and sharing with colleagues and clients. My screen real estate gets pretty crowded very quickly.
One of the challenges I face is trying to keep some sort of order in front of me on the screen while working. When trying different design ideas in Enscape it is common for me to keep Setting, Materials and Assets open, and I am constantly sliding windows out of the way to find what I need.
Have you given any thoughts to the possibility of including a window management option where any setting, material, asset UI's may be collected under one "tray" or "tabbed tray" similar to/or better than SketchUp or Revit?
