@twojays @moshimotsu sure they will, any app look exactly like them are. I was talking about my and system apps but I already wrote the system ones like files, terminal, text editor and calculator and I am working on a store, the only app that will still use libadwaita is Bottles (for now, actually I am working on integrating it deeply in the OS directly, but that's another thing, also Bottles Next is a thing).

Like I do not like to be forced on a way, I am not forcing themes in other apps.
