Not at all clear if this is an apple issue or not, but the reality is that the change to Apple Silicon and other (arguably for the better) changes to MacOS have made the functionality of TS increasingly difficult for an independent developer to create. It would be great if Apple just acknowledged that Mission Control has been in a downward spiral for years, and invested the developer time to produce a window manager at feature parity with the myriad of options in Linux distributions. With the army of developers at Apple, I have to believe there are many who understand what fully-featured window management functionality is. For me TotalSpaces has for almost a decade plugged the hole left by Apple's increasingly bastardized offering. It's a shame to see the talented independent developer of TS get squeezed out by Apple and no real competitive offering make it into MacOS.
