On the admin site, I want the tag list view to include counts for how many times its used, in order to understand the scope of tags and clean them.

testing notes

In django admin, go to the list of tags:

• confirm you see a count for each tag
• confirm you can sort by count

Is your feature request related to a problem? Please describe.
In #506 we asked for a tag merge solution. But before we merge tags, it would be helpful to understand the spread, scope, and overlap of existing tags.

Describe the solution you'd like
Similar to how the language+script list view is, it would be great to add a column to the tag list view with numbers of how often the tag is used.

dev notes

Should be similar to implementation with LanguageScriptAdmin and queryset annotated with Count.

Possibly additional complication that we're using default taggit admin view — will likely have to extend the default taggit admin model object, unregister their version, and register the customized version. It seems unlikely a custom admin model queryset will impact the autocomplete keyword lookup speed, but should be tested.

@rlskoeser - this is great! I think we can close this issue now, then can we get a CSV download of just the categories that show up on this tag list view/would it be easy to implement that as a command for this page in general?

[rlskoeser]

@richmanrachel what's the use case for a CSV export of tags?

[richmanrachel]

@rlskoeser - so that we can re-sort by name, for example, to determine which tags need to be merged. And to identify which of the lesser used tags should be deleted.

[rlskoeser]

@richmanrachel you can sort tags by name in the admin site, which is a better place to work with them and do cleanup.

@rlskoeser - oh, fantastic! you're right. No problem then :)
