It should be possible to inspect a note by an ID using the plugin by:
- Opening the panel with at least one note selected
- Clicking on the table header
- Pasting a different ID
- Pressing "GO".
(Make sure you have a backup before doing this).
In Joplin's sync errors page, it might also make sense to add an "ignore" button by decryption errors in sync status (like we have for other types of sync errors).
