AFAIK waybar doesn't offer quick launch buttons, but it does offer custom modules, which one can use to mimic such buttons. I'm using custom modules in a pretty simple way, for example for librewolf (I didn't find an awesome icon font for it, so using the FF one):

    "custom/librewolf": {
        "format": "",
        "interval": "once",
        "on-click": "librewolf",
    },

I have some other ones for other applications. I do use keybindings as well, and I can use wofi to search for the applications, but none of them are really alternatives for other users.

It does work ! However I was looking for a very simple way to add what official modules, like a "tooltip-format" which is part of the official modules. Not sure why on earth it's not part of the custom modules. So for example, I'd look for something similar to:

    "custom/librewolf": {
        "format": "",
        "tooltip-format" "Librewolf Browser"
        "interval": "once",
        "on-click": "librewolf",
    },

So that if someone doesn't recognize the awesome font icon, one could just find out by the tip shown when getting the mouse on top of the button. As this is not supported. Is there any simple way to do that? Hopefully not requiring to add several scripts just for this. Something that might be part of such snippet, and pretty simple would be great, 🙂

Please let me know of suggestions.

Thanks !
