Sometimes there are approval categories which are mainly used by bots. In some cases, users need to override bot score. For example, fix a false negative result. Users will have all approval categories listed when they are publishing comments. This easily leads to mistakes when users accidentally publish too many approvals.
User experience could be improved and chance for errors reduced if "secondary" categories would be hidden by default. Approval categories indented for users would be always visible and categories indented for bots would be folded in the UI.
