Hmm... let me tell you what I think is your situation, and you tell me if I understand it correctly.
1. you have a folder "FolderToggle" in the extensions folder, and inside are folders "profile1" and "profile2", with a config file and two sh scripts, show.sh and hide.sh. You have written "Special" (no quotes) in the first line of the config file in the folder "profile1"
2. You have a folder called Special in documents, with books inside that you want to show and hide
3. you have edited the menu.json to be in german, only changing the "name" values, without touching the action.
Is this correct?
