@Natanox oh my word this triggered a memory of the dumbest hack I did as a kid. If you copied Firefox.exe and then opened the copy with a hex editor, there was byte you could change that would make it so they were treated as two completely different apps. Changed the icon of the copy so it would feel like an entirely separate/new app.

Don't even remember my use case. Is this kind of what you're talking about? A distinct app that's basically a forum focused web browser?
