Feature Request:
How about a Cancel button for cleaners with warning dialogs!
How this currently works:
If you press the [X] close button it will still enable the cleaner instead of what I'd logically expect to happen which is not enable it.
How this could work with my feature request:
After including a Cancel button also allow the already existing [X] close button to work exactly the same as the Cancel button meaning; The user has heeded the warning dialog, and has decided not to enable it.
