Up until now, plugins trying to “embed” obsidian own editor functionalities (like kanban and excalidraw) have to replicate the parsing and logic themselves. I think to fully allow an heptabase-like plugin to exist is the ability to iframe multiple full obsidian editor view. Obsidian editor view must become embaddable and “aware” of it’s surrounding so as to allow graceful resizing and two way communication.
I would totally love the support to make such a plugin possible, but then whole functionality won’t be further enriched by the community. If the functionality becomes core however, then plugins and full community can further enrich the experience
