Have the developers considered adding the Fopnu protocol into Tixati? Tixati already has a search function for joined chat channels. If that was replaced with the Fopnu protocol, it'd allow a rapid increase in its use. It's just an idea, I don't know how difficult the coding,however, I think it'd be worth it, at-least in my humble opinion.

This is definitely under consideration, and I would probably have already done it if it was easy, but the two models of sharing do not fit together well.  The library in Fopnu is so much different than the Shared part of Tixati, which is just links and text.  And there other major differences like the way uploads are organized.  So a very very careful design would be needed.
