They take good notice of everything on the Whilist here. And Pseudo elements aren’t a little thing to bring into Webflow, but definitely a need more than ever, now that we have dynamic lists.
So my advice is never to wait for features, work as if they don’t exist so you won’t be disappointed. As Webflow grows more and more complex it’s barely impossible for them to disclose any roadmap, that’s easily understandable.
I recommend to watch Nelson’s workshop with Webflow CEO Vlad Magdalin, a lot of things for Webflows’ future are disclosed in this video https://webflow.com/workshop/qa-with-webflow-ceo-vlad-magdalin
