Hi,
You are correct -  options are not associated with folders.
- You can safely delete your new options folder without losing the data
- A few different options:
     - Create folders that have restrictions, ie in folder properties set a filter for what is displayed there (you'd have to set up your options in such a way that you can filter into your groups)
     - Extend the xtk:option schema to add support for folders. Never tried it for options specifically, but should be doable.
Regards,
Jonas
