Display selected categories at top of publish category tab

Question

We have over 1000 categories visible on the Publish Form (inherited!). I want to be able to show the moderators the selected categories at a glance instead of them having to scroll through all 1000. Is there an extension out there that does this, or will I have to roll my own?

Answer 1

Unfortuantely I don't know of any addons that will do this, however using the instructions field you could inject some javascript into the publish page. Something like this would probably get you a good chunk of the way there.
