Delete Miniworld

[skeygeta]

I'm sure there was an option to delete a miniworld before version 1.x but after updating, restarting the game by deleteing all save data I can't figure out how to delete them anymore. I only find the "reset" option, but thats not what I need as I want to create a new world with a custom name on the -first- slot where the "great wilds" is saved on default. So I have to delete this world first. But how?
