[rolelicense] Discussion: other features?

[calebj]

I did a small commission for someone, a cog that can generate "license keys" for roles that can be redeemed later. I'll be publishing it once I'm happy with it, but I'd like some comments on what I have so far.

The following features are complete:

• [x] Add and disable redeemable roles
• [x] Generate keys and DM to requesting admin
  • [x] Custom key "templates"
  • [x] As messages or a text file
  • [x] Restricted to Administrator permission
• [x] Track used keys, who redeemed them and when
• [x] Transfer unused keys of one role to another

And the following are planned:

• [ ] Display/report/logs of key redemption
• [ ] Timed roles
  • Using additional keys will add more time
• [ ] List all redeemable roles and un/used key count
• [ ] A way to mark keys as "distributed", by who and when
  • [ ] Commands to pick from the list of "undistributed" keys
• [ ] A way to tag or group keys when generated
• [ ] Use sqlite instead of JSON
• [ ] CSV or plaintext import of keys from a file

What else should I add?
