@weirdwriter @rigrig@tubul.net While there is no built-in webclient, current frontend and accessibility efforts are focused on the instance's public pages, like profiles and threads, and the built-in interface for user and admin settings.
I do have ideas/code for a fediverse client in the long-term, but it'll be a separate project (with first-class GoToSocial support). Also lots of the current frontend structure and knowledge will be transferable there.
