Use case or problem
Provide GUI interface for YML metadata.
Proposed solution
See how Saga.so uses Properties with configurable properties that can be added/removed.
https://www.reddit.com/link/m2znjs/video/bnqrxguthgm61/player
Hide YML metadata by default and expose it through this feature.
Provide setting to show YML metadata in edit mode.
Current workaround (optional)
Manually edit YML metadata which is always displayed at top of file
NOTE
This is not a request to remove or replace YML metadata with another system.
This is only a request to hide the YML metadata when viewed in Obsidian.
Opening the underlying markdown file in another editor should show the YML metadata still intact.
