– the panels disposition cannot be recovered in BFA
It’s apparently saved because the panels are there if the file read in any version of Blender but not in BFA.
I have thought about this again. Can it be that you expect to store the UI in the blend file, and reload it with opening the blend fine? Because that’s a default setting that we have turned off in Bforartists. It’s confusing for newcomers when the UI goes crazy by loading a blend file.
When you want to have this behaviour back, then you can simply turn it on in the user preferences again.
