FEATURE REQUEST: Delete unused tags instead of returning in the list of potential tags

In keeping tags organized, it would be helpful if, when a lookup is done in the Wagtail admin while typing a tag name, any tag that is found that is not connected to any items would be deleted.

if tag.taggit_taggeditem_items.count() == 0:
    tag.delete()

For example, if someone typed “Newsletters” for a tag name but decides that it should really be “Newsletter”, “Newsletters” is continually returned along with the preferred “Newsletter” even though “Newsletters” is no longer used as a tag. This will likely result in user confusion and possible mis-classification on future document uploads.

@ababic, yes, I’ll look into that.

I just discovered that there is now a recipe in the Wagtail docs that, while not automatic as I had first proposed, provides the functionality needed to accomplish what is needed. Closing this feature request.
