The new #Pachli Current implements a suggestion from @blitter, and shows an account's pronouns.
This is a feature from #glitchsoc, also in (at least) @apps and @moshidon.
Pronouns are shown in the "account info" area at the top of each post or notification, so this area has been redesigned slightly. The account's handle now always appears on the second line.
They're also shown when replying to an existing post, the auto-complete popup, and when searching for posts.
