@mdubakov I am really happy to see this progress 
However, I was wondering if you have considered a more granular block layout similar to what many other tools have adopted (innos.io comes to mind as one the most recent ones) where headings, text paragraphs, individual bullets, views, code blocks, etc. are all individual blocks rather than a single larger block. I know this creates a bit more visual clutter but I believe this provides the most flexibility when it comes to transclusion and block references. You often don’t know what part of the whole you may be trying to reference in the future and having individual items in a nested bulleted list available for reference.
The ability to fold indented items is also something that I really miss in comparison to other tools (particularly roam’s which seems the most mature) and can be really helpful when you are using a rich text area as a presentation/collaboration tool while sharing screens:
