Unused Add-ons (We Could Use a Trade-in/Upgrade System)

Demodorkin

No one needs this many combs or origami swans. :P

It would be useful if we could exchange a certain number of add-ons for a single (random?) add-on of the next tier (eg. X Commons for 1 Uncommon).

Even with an exchange rate of 50:1, you can see how it would clean up the surplus of unused add-ons that accumulate in the player's inventory.

Edit: my original post was removed... not sure why. Apologies is this results in a double-post.
