If I quit Joplin and delete the ~/.config/Joplin folder, the folder and its contents are recreated at the next app startup (in the screenshot all files / folders have the same modified date). Should this happen if the Electron state has been moved to the ~/.config/joplin-desktop/internal/ folder?
I only found this as in Linux the Markdown editor spellchecker has stopped working and I was trying to work out whether it was my system or Joplin.
