Nested Note and Nested Relations Lines in Canvas like Plectica's DSRP

Use case or problem

I am so excited about canvas plugin. I think the features from visual system thinking pkm, https://www.plectica.com/ , is excellent and can be adapted to Canvas. It uses DSRP (Distinctions, Systems, Relationships, and Perspectives). It could do things like this:

  1. Relationships = To show the relationships, and the notes can also be nested and put inside the line connecting to other notes (so the line showing relationships could be made more complex).
  2. Perspectives = Eyes indicating which perspectives are used to see a note. It could be used to generate multiple perspectives on one thing/note

The example is like the images down below.
