The first thing I wanna see in forum in 2023 not only 2023 but I always hoped that the forum would bring the option of two factor authentication. I think nowadays most of us are victims of phishing in various ways and if there is two factor authentication I think it can be a bit more secure from this side.
Also, there is one more thing I would like to see and that is to improve the responsive display aspect. Because it has been seen that many times when we create a post on pc it's all ok in pc but when we open that post in mobile the post became vice versa.
