Is your feature request related to a problem? Please describe.
The use of tags offers many surprising possibilities in a functional concept. It's great that you can add images to tags, even a 'teaser image' and a 'full image', even versioning is possible - all very nice! - Wouldn't it be consistent with Joomla logic to also enable custom fields for tags in order to be able to expand the content structure of tags using board resources?
