@Halil Ozercan I've been going through the BTF2 docs, and one thing I haven't seen a way to do yet, is handle rendering custom spans. For instance, a use case I'm very interested in is providing a spell check span. So I want to be able to render some custom underline, the standard red squiggle. Then I want to be able to treat it like a link, in that I want click callbacks for it. I haven't seen a good way to provide custom rendering for spans, unless I'm missing something?
