Yes, but doing it properly is vastly more complicated than adding a checkbox (for reasons explained in some very long threads here). We've made some progress on the dependent parts and hope to offer something in the not-too-distant future.
Sorry, I may have missed something here, but where does it say what is being planned in this regard? I'm working on another open source project and am trying to export docx/odt files with Zotero citations and the lack of the "author (year)" seems to set Zotero apart from a lot of other citation systems, so I'm wondering how to best translate this or whether it's best to just wait until this has been implemented in Zotero. But I can see that this issue has come up regularly over the past 15+ years, so maybe it's something that is more of a long-term goal and I should try to come up with a temporary solution until then?
