Bases: Treat Canvas nodes/cards as queryable entries

Use case

It would be useful to query Canvas:

  • text cards

  • file cards

  • link cards

  • groups

For example, show all text cards matching a tag, all cards referencing a particular note, or all nodes within a given Canvas.

Proposed solution

Allow Canvas nodes to be used as Base entries with fields like:

  • containing Canvas

  • node ID/type

  • text/content

  • referenced file or URL

  • group

This could fit a broader model where Bases can query structured entities below the file level.

Current workaround

Parse Canvas JSON with a plugin/script or duplicate Canvas content into Markdown notes.
