I have two friends who often play minecraft on my computer. They don't have their own accounts, but they want their worlds separate from mine without the hassle of moving around save files. I have already set up two new profiles like this:
Jack
Ethan
Joe
Jack has one world, spartacus. Ethan has two worlds, City and Tests. I have one world, Pure survival. I want them and me to be able to get to their worlds, and only our worlds when we select our profiles in the new launcher, no save file moving involved. How can I do this? I am confident that this is able to be done in the new launcher, but correct me if I'm wrong. As always, thanks! Also here is what I have already tried: I tried making a main-Minecraft file in the roaming directory, which contained three folders, each labeled with the name of me and my friends. Inside each of these files is a copy of the .minecraft folder, each saves folder containing each of me and my friends worlds. I was extremely sketchy about this though, as I didn't know if it would corrupt the game.
Edit: Turns out sharing an account is against the EULA.

You can set the Minecraft Directory in the Profile Editor.
Go to "Edit Profile", and check "Game Directory" for each profile. The game will create new folders for saves, resourcepacks and logs. It will continue to use the appropriate version you selected for the profile (found in the "versions" folder), rather than download the game files again.
You can then move the saves you have to the save folders for the correct profile.
