TBH, we still need to see how it integrates with the keyboard.
Ever since I've been using a Mac since Nov. 2023 that's been one of the things that I've battled with, and I've assigned a heck tons of shortcuts to make that happen.
It's frustrating at best. On any tiling WM on Linux, I can hit Meta+<#> and be taken to that workspace.
On macOS, the moment I fullscreen an app, it's taken out of that flow. So for so many years, I've had my terminal full screen on workspace 2. Meta+2 it in my muscle memory for "go to terminal".
Wouldn’t it be like everything else, default keyboard shortcuts that can be easily overridden? Personally I hope they go with rectangle’s CTRL+OPT just because it’s seared into my muscle memory now
