I guess the main improvement is that the panels and sidebars don’t cover the desktop, so you can edit all of it more easily.
To me the most annoying thing with edit mode was that auto-hide panels would still hide in edit mode, making them difficult to edit, but that was also fixed a little earlier.
Maybe missing something but it seems like it mostly adds fancy animations like zooming out the desktop and sliding items around.
It looks nice but it looks like quite a superifical redesign of edit mode? But in fairness it may feel more effective in use.
But my issues with edit mode are not the ones described in the short post, so probably why it doesn’t speak to me much.
