Yea flatpaks are great, I use a few on my manjaro install (the way manjaro releases packages makes it sometimes the only real option which is one thing that made me consider getting away from manjaro, despite how much I like it ;_;), but some make me paranoid, even if it is something non-critical like an emulator. For example, I do not use the dolphin emulator flatpak; it worries me it has full system read access and ones like duckstation work just fine without that. Fortunately, I find the dolphin core works perfect in retroarch, so don't need it anyway. Maybe I'm just paranoid?
