Currently, when adding identities, there is only a very limited list of titles to choose from. Here is a screenshot from the browser extension showing the complete list of available titles:
Expanding this could allow using increasingly common gender-neutral honorifics like Mx. as well as the many other honorifics out there (e.g. Miss, Sir, Rabbi, Father, Imam). If you don’t want to maintain a giant list of honorifics, perhaps it makes more sense to have a write-in option here instead of limiting it to just the pre-set titles.
