Is your feature request related to a problem? Please describe.
I once bought an Optifine cape, and i can't use it in Iris, sadly.

Describe the solution you'd like
I would like that there is a cape tab like in Optifine so that people can use their Optifine capes in Iris.

Describe alternatives you've considered
I have tried a fabric mod called Kappa, but it doesn't show my Optifine cape, instead it shows my migrator cape.

Iris will not be adding optifine capes, to get kappa to work properly you need to disable your migrator cape

oooh ok, thanks a lot
