We introduced pronouns support in #Fedilab recently thanks to a suggestion (https://codeberg.org/tom79/Fedilab/issues/1028)
@megalodon is the first app that worked on it.
We extended that beautiful idea to some views where we thought it could be useful (when replying or when searching for mentions).
We will do our best to contribute with other apps for a kind of normalisation of this feature (especially for the localisation around the English word "pronouns").
