[Cialug] Flatpack repos?

[David Champion]

I've been using Linux since before a lot of you whippersnappers were born,
but I'm new to the Flatpack thing.

As a SteamOS user I would like to add some apps, but I'm finding that the
default flathub repo is somewhat lacking, especially when it comes to what
I'd consider to be common CLI programs.

Do any of you Flatpack fans have some recommendations of good / reliable
flatpack repos you use?

Thanks,
