Or you could also make your own cape system, I would definitely buy it ;)

No. Why would we care that you donated to someone else?

You can use other mods if you really want to see your cape.

More importantly, we're not interested in "selling" cosmetic features. We have donations, but I don't believe that a donation is really a donation if you're getting things for reward.

If you want to donate ex-gratia (without reward) then you can do so via the button we added to the Video Settings screen.
