Helpful, but incomplete. Please add a little more.

This plugin does exactly what I need fundamentally. But I can’t find way to edit categories and tags after they have been added, or to filter by a category or tag from the filter bar above the list of coupons. The reason I need to the later is that some categories don’t appear until page 5 or 6 in my list of coupons (we have a lot) and so it’s tedious to page through the coupons until I find one with the category I need just to get a list of coupons of that category. IF these features existed, it would seal the deal. As it is right now, it’s quite frustrating.
