Print dialog page to have a button for "print current page".
I almost always want to print just the current page of a diagram. It seems there's plenty of real estate on the print page to have a "print current page" button - especially with modern sized monitors. Either that or the document dropdown menu under settings could stick at the last used value.
It would stop me being annoyed every time I print something plus save the planet some paper when I occasionally print all pages of a large multi page diagram.

Make it default to print only the current tab, instead of printing all tabs per defult!
