I would love this FR, and there are a few other similar FRs on the forum too
- YAML YAML, Go Away - #6 by demeneer
- Hiding YAML in Edit Mode
- Ignore YAML in viewer
- and a FR on the Metatable plugin GitHub
One possibility could be a snippet with the “.is-live-preview” class that hides the YAML section, and then using the Snippet Commands plugin hotkey to activate/disactivate the YAML display as needed.
I would love to learn how to do it, but I wouldn’t wait for me!
