8e1018de2c
Implemented for Global, Virtual Desktop and Application layout policies. Not implemented for Window policy due separate windows do not preserve their IDs between sessions (still could be implemented the same way as for Application policy). Layout saving/restoring happens on Session save/load. Covered by unit tests
