A True Graph Note-taking App and RemNote Features

A true graph-based note taking app need these features in data storage layer:

• Independent nodes
• Edges between nodes

And the features on UI:

• Create independent nodes
• Linking between node
• Pin nodes to top level
• Reference to a node, and expandable reference to node

RemNote is quite a good graph-based note-taking app with all those required for graph-based note taking:

• Data storage
• Each top-level note is a node
• Reference and portal to make linking
• UI features
• Very easy to create independent node, click Create button
• Linking between nodes are based on references and portals
• Pin to top level
• With ref and expandable ref
• Even better
• Create nested items as nodes
• Linking even to nested items inside node
• Pin a node or pin a nested item are both ok
• Ref and portal can be created to note or nested item

If considering Wiki-like as a graph of article, RemNote is better:

• Each nested item in note (article concept in wiki) can be a node too.
