An alternative approach to #2582, as suggested by Joel and supported by Pete. Felt multiple PRs would be better here, to allow us to compare the different versions more directly.
Overall it looks nice, but future refactors to make a layout shared would still often be slightly more involved than dragging and dropping into the shared folder - multiple layouts present = need to be uncoupled.
