Because you can use assets from other people made ahead of time aslong as you give credit it should totally be fair to make your own assets now especially since you dont even know your themes yet so its not that op. I am not an admin though.
That's what i was thinking tbh. Like if i can use other people's assets why wouldn't i be able to use my own either from old projects or made for no particular reason Though i should probably ask the admins directly maybe since there's a chance they wont read this
