Save Opened files in Temporary Folder
@Pesala But that only really applies to PDFs. Old Opera I believe had this option for all files, regardless of type. So if you were about to download a Word doc and you press "Open", it would save the doc in a temporary folder and open it in Word.
I'd say that I delete at least 50% of all files I download after I have viewed them, so making "Open" only store files temporarily would be amazing.
