Disable auto-save

When I work on some files, I dont want to save it after closing the document… If I want to save changes, I can save… But when I dont want to save changes, what must I do?
I dont want auto-save… Is there a way to do this? If not, do you plan to add this feature?

For all apps.

If you are comfortable in Terminal.app you can try (AT YOUR OWN RISK )

Quit Hype.

Run in Terminal.

defaults write com.tumult.Hype2 ApplePersistence -bool NO

This seems to work. But note that this may get overwritten with updates.
To revert back.

I am unsure how this affects auto saves on crashed apps or Macs.
Meaning all that work you did when you had that crash may not be restored.

defaults write com.tumult.Hype2 ApplePersistence -bool YES

There is also no guarantee that this option will always work with new OS or app updates.
