Preferably with more than one possible language selection, it'd be nice to be able to filter streams by language and get rid of every streams we wouldn't even be able to understand.
I found #10 out, but must be really blind as despite looking on many places, I was unable to find any language settings other than the one to change UI's language. So maybe this was removed after some time, or I didn't understood well that it was implemented, or UX could be a bit improved on the matter?
