Recently when I edit in an external editor (NotePad ++) and close/save NotePad++, returning to Joplin, my edits are intact, but the external editor button doesn't close the note, and so the external edit icon remains with the Note title, as such...
Has the process for external editing chnaged? How to I get rid of
If what you want is to automatically cancel the synchronization after the editor is closed to edit this text, you can consider switching to vscode and use a plugin to support this operation.
