I've tried Yabai, Amethyst, and AeroSpace, but none of them support tag-based workspace management. That was the main reason.

The concept is best explained in the River documentation: https://codeberg.org/river/wiki-classic/src/branch/main/page...

As far as I know, not many WMs adopt this paradigm (mostly dwm, awesome, and river), and Yashiki is likely the only one on macOS.
