You could probably do it pretty easily in Hyprland with the monocle layout and making SUPER+[current_workspace_nr] switch to the next application by adding some lua to your keybinds.

Do you mean that as in, having 10 applications bound to 0-9, and being able to cycle through instances of that application by repeatedly pressing the corresponding number in the number row?

Except when they are shit and contain stuff such as #everyone_dies and #main_character_dies, like the default metadata source for Jellyfin and some torrent aggregators do.
