Build viewer too

[ghost]

Or there's some reason not to?

Uhm. Nothing in the way really. Although I would prefer to have it as a stand-alone flatpak bundle in that case.

@JerryCasiano What's your idea?

I think either way would be fine.

The main application does call the viewer over dbus if a user tries to open a single font file using it, so it probably should be available.

It's also useful for people who don't really need a full manager but want the viewer.

So if it can be done in a separate package that would probably be the way to go I think.
