I think I know what's going on here, but I need some more info to confirm. Are you able to get a list of running clients out, and see what the window class & title for the duplicate actually is please?

I suspect that doesn't match the value in favorites so it doesn't know to group them.

I was actually able to fix it earlier today.
I had added "codium" in my favorite list, but when I run wlrctl toplevel list I saw that codium was named codium-url-handler.
When I put that line it then it grouped the icon properly. This seems to be case-sensitive since I had to change "alacritty" to "Alacritty".

You may well find that although that fixes the grouping, it breaks the ability to launch the program, unless xdg-open is smart enough to handle that?

From what I can see it seems to work well enough.
All of the icons I have in the launcher is able to start from clicking on the icon.
But while it works I do feel like this is a workaround more then a fix?

For reference this is what I have in my config currently

   "favorites": [
      "firefox",
      "WebCord",
      "steam",
      "codium-url-handler",
      "Element",
      "Alacritty"
    ],

Good to hear, thanks for confirming. Hopefully that saves me a bit of a headache.

Agreed, it's not obvious or ergonomic at the moment. The problem is some windows just don't have names that match their binaries, and it's not very obvious what you should use where without scouting through with your compositor's IPC. I'm open to ideas about how to improve it.

I have limited knowledge on this, but when I saw trying to trouble shoot this I did see that (most) .desktop files has a StartupWMClass variable that might help: https://askubuntu.com/questions/367396/what-does-the-startupwmclass-field-of-a-desktop-file-represent

With that said I did see that not all of mine .desktop file had this variable. In this case it was steam and codium-url-handler .desktop files that did not have it.
Mind you I also see that codium have 2 .desktop files, one for codium and one for codium-url-handler.
I don't know if me using NixOS that effects this, but I guess I should put it out there.

StartupWMClass is a legacy X11 concept, so it only gets applied to XWayland windows. I think it's also just a hint, and the window can set its class at some point later in the process anyway.

In the Wayland world, each window gets an app_id instead (so I end up having to look at both because XWayland isn't going away any time soon...).

It's not very clear whether Wayland abides by StartupWMClass at all, and I suspect it's on a per-application level. Still, that's an avenue worth exploring and might catch a few edge-cases, so I'll definitely look into it. Cheers for the pointer.

Make sense to centralize it to that issue.
My only opinion for how is that you might want to add a warning in the documentary that says that favorites is case sensitive, and that the window/appid might have a different starting name then expected.
