Hello!
Interesting topic.
What I need for my use case is either a block to block link and/or a feature to embed a “part” of an object inside another object without having to turn it into another type of object. This embed would have to be expandable. A good description of this is here :
Better object preview on link hover
This feature is necessary for keeping track of which paragraph of a resource was used to write a specific part of an article, mainly for faster referencing. Also, it’s necessary for keeping track of citation information. For the citation part, of course some sort of manipulation of pdfs needs to be introduced. For example, in Remnote, we can click and drag to select a part of a pdf, and have the option to either only highlight that part or link that part to a “Rem” which is what a bullet point of an outline is called in Remnote.
If block to block links can’t be done with Anytype’s architecture then the embed feature is a must for me.
Anytype is already very good at taking small amount of info that is added each day and then link the same type of those small info together and make a coherent, “permanent note”. Like, adding daily thoughts or literature notes (useing Zettlekasten terminology for lack of better option 
) from literatures etc, and add them together to make a new content. But, I think, it still needs to add some features for adequately managing the knowledge that comes to us as a bundle not bite size info, like school, college and different courses. And, I think embed/ portal is one such feature.
Edit: Just to clarify, The embedded portal and referencing may be different, although similar, features.
The other one is handwriting with diagramming. Some information is just better to organize visuo-spatially. And that is really needed. Here are some feature request (one by me 
)
Many good wishes to the team during this busy time. I wish I could do more to help. But joining the Nightly types will have to wait for me due to time constraints on my part. 
Good wishes and thanks.
