👋 Hi guys. By the chance, is there somebody who’s working on some simple rich text editor?

I don't think I'm aware of that. I think most people use TextArea as is. Were you thinking about writing one? Or were you hoping to find one? If I was looking for one for my own project, I'd probably search the web for an existing JS library (I assume one exists but I haven't checked) and import it, adding any bindings to it if necessary.
