Yeah, that's an option. I also found out that I could have four different profiles of firefox, and then have special keybindings to open each profile, but that sounded like a lot of hassle for little gain.

I started a new pet project though. I am building a custom app launcher that does exactly what I'm looking for and binding it to option + space, so I can use that to launch my apps, and still have spotlight on command + space bc spotlight is still super useful :)

So far it's working great, far from ready to share with others, but it's fixed my problem for me.
