+-- By default awesome forgets window positions when you switch between layouts, this is especially a problem
+-- for floating layout, which awesome wasn't designed to handle gracefully out of the box. This tidbit of code
+-- fixes that issue by remembering window positions in floating layout and coming back to the same positions when
+-- you return to floating layout from a tiling one.
