I just wanted to return to add an idea, and maybe a feature request. It may be helpful to have a "Save without changes" (good) or a "Close without saving" (better) menu item. Currently, Ctrl + W (Close) asks, "The document is about to close, would you like to save your changes?" with the options of Yes, No, Cancel. Of course, No means "I'd like to close this document without saving my changes." I often open a document to do nothing more than view it, then select + copy a layer, then close it. With no other changes made, I'd like to close this document very quickly. The prompt slows this process down for me. An option specifically for closing a document without saving any changes -- no prompts needed -- would be helpful. Also, it seems the keyboard shortcut of Ctrl + Alt + S is available for such an option.
If this option seems too radical, a post prompt could be helpful: Ctrl + Alt + S, then a prompt saying "Close document without saving?" and Yes/No options, where the Enter key = yes, and Esc = no, do nothing.
Side note: I'm not sure if anyone else does this, but even though I know I don't want to save any changes, just the very presence of the prompt makes me read it then spend a moment contemplating carefully on which option to select as to not make a mistake.
Thank you.
