As content is at the core of any platform, I feel most feature requests on this community now revolve around consuming content while it should be primarily about creating content. I didn't see many issues on github regarding content creation either.
I personally would love to see an 'edit' and 'delete' option for OPs, as that's currently not possible from within wefwef. It is possible to edit and delete comments, but for OPs one needs to visit the web interface of Lemmy.
I slightly less annoyance is the situation where some software keyboards overlap the text when an OP or a comments is added. Specifically if it concerns longer OPs and comments.
