Hey,
I'm using your gread off for two years now. I have now more than 200 licenses running and it is really horrible to mangae them or to find on sepcific.It would be awsome if it could be possible to have an option on your website to organize the licenses. So I would recomend to allow a user to add a set of tags to any license and to give a user the option to filter all licenses for one or several tags.
