A nice feature in jrTags would be a way to limit tagging only to admins. Purpose of this feature would be to enable uniform and consistent tagging throughout the site.
Often one user gets 'tagging happy' and can create dozens of different tags for his items. Also there are just different spellings and ways to tag things which can produce many unwanted tags.
Currently if 'Allowed to Add Tags' is not checked for a quota, then even the admin can not add tag to items owned by this quota. Also tag labels are not displayed under item on detail pages of this quota (if already added), although they do exist in cloud.
Know that tags are made for 'crowdsourcing navigation'( https://www.jamroom.net/the-jamroom-network/forum/suggestions/8482/tag-creation-item-create-update-form)
but see above reasons why some might prefer otherwise. Also know that a custom keyword field can be added with form designer but JRtags has many useful features.
An idea might be to have three check boxes in JRtags quotas page
1 - Show on Detail Pages
2 - Allow tags to be added to items
3 - Allowed to Add Tags (would work slightly different then now; admin would still be able to add tags to items owned by quota even if unchecked and tags would display on detail pages even if unchecked).
