Create Snapping Grid with auto resizing of snap area shortcuts

Please see the following screenshot: Manually autoresizing them is rather cumbersome. It would be great if you could set a grid area (e.g. 3x3) with defined height and width and place it anywhere on the screen (you could use UIStackViews for this). Then, you could just add your snapping areas to the grid and place them to your liking with autosizing.
