With bigger displays like my 5K utrawide the Window Manager current Third and Quarter are not sufficient. There should be at least 1/6 and 1/8 or even smaller. Best solution would be the ability to save window position per application, so that one click in Window Manager would arrange all open apps to their pre-defined position.
Exactly what I need as well. This functionality only exists in this app https://apps.apple.com/us/app/stay/id435410196 and it is very useful, especially for multi 4k external monitors on M1 pro
