I think the Editor needs two dialog windows added to ask the user about saving.

1. When closing the editor, if you have unsaved changes to your world, it should ask you if you want to save or cancel closing. I have accidently closed the editor too many times.

2. When saving your world, it should ask you if you want to save over an existing world if it already exists. I have accidently saved over worlds before by just clicking on the wrong one and losing a bunch of work.

yeah (ill add this to roadmap)
