Close file capability

There are times that the changes / enhancements made to a photo by Photo AI are not wanted or big enough improvments to need to change, however there is no way to just close the photo and not accept the changes other than quitting the application. When working with this as a plugin in Adobe Lightroom, this still creates and leaves a Tiff file that must then be deleted. Could you please add a button or menu item to close the file without saving and have it automatically delete the Tiff file that gets created in LR.
