Feature Request: Update canvas functionality

[heavenideas]

Issue:
You can create a canvas from a given note using a plugin. However, as you continue to link other notes to the initial note throughout the course of working on your Obsidian vault, you may want to update the canvas with new connections. The problem is that you may have already moved notes around, added extra notes that might not be directly linked through backlinks, and so on.

Proposed solution:
It would be helpful to have a way to "update" the current canvas so that it can create new cards that are connected to the main note without creating duplicates or disturbing the cards already present in the canvas. This feature would be a great addition alongside the "Feature request: add link exploder functionality to cards on the canvas." #5

Caveats:
I understand that one of the biggest issues with this feature would be how do you know where to position any new cards generated by the update action. Potentially you could prompt the user with which main direction they would like to add the new cards: top, bottom, left, right. For example

Thanks again for creating this plugin. This has the potential to be an amazing companion plugin for canvas

As a first version, even a shortcut to wiping the prior canvas and recreating canvas would be great.

I second this request, that feature would be very helpful!
