It is possible to diff an existing file against another file, or a modified file against the original file on disk. What I am missing right now is an option to diff two open tabs, no matter if they are already saved or not. This can be useful if you are pasting some text from two different sources and want to compare it. Right now you first have to save the text to be able to use this feature, even if that's not what you ultimately want to do.
