Correct me if I'm wrong, but once kbin is federating properly shouldn't it be possible to view and interact with the content from Kbin? Or is there a technical limitation for that on the app?

Yes, it's called Jerboa. Using it now. Shockingly decent for being in alpha.

Would love to see 2-factor authentication (app-based) implemented at some point. Not a pressing issue right now, but once everything stabilizes I think it would be a valuable security feature long-term.
