I think I’ve seen this being used in a build I downloaded on GraphicAll, which felt very rewarding - though it could be leeching preferences from somewhere else. Either way, glad to have pleased one person at least.
I could brag about the plethora of layouts improving upon the original 5 (animation, model, material, ssequence, scripting) but the layout is really a personal space that I enjoy using. However you like splitting up your screen is great. In fact, I’d love to see some other people’s personally tailored layouts to improve upon the ones I made. I like them to be generally good for all people to use as a sandbox for any project since I give people Blender frequently.
