Feature Request: Last session per User

[loaidheach]

It would be nice if the last session could be stored on a per user basis. I haven't looked at the code in detail, but in looks like it should be relatively easy to implement. Apart from changing the session when the user select is changed (via notify::selected), the cache.json would need a different format, e.g.

{
  "user": "someguy",
  "sessions": {
    "someguy": "Hyprland",
    "otherguy": "sway"
  }
}
