More Minecraft Accounts (for minecraft java)

When you create a minecraft account, you can create "Profiles", the profiles work like: Who is playing "Creeper01" or "Creeper02". Each of the profiles would have a different progress in the saved worlds, it would be easier (even more for a family that has minecraft java or a player who wants to have 2 profiles), to make it easier and not keep creating so many worlds, and there would be a limit of profile 4, they could also add skins for each profile. Hope you like the idea :)
