Give option for perticular document to remain landscape or potraite.
Very important for phone users, because we can barely see the text in portrait mode! It's annoying to have to switch the entire phone each time, when you only want to change the document.

For those scanned pdfs, view them in landscape mode is a must-have option.

Why does Xodo print my document that is in landscape orientation, in portrait orientation instead?
