It would be an excellent functionality if you could import PDFs and powerpoints as imiges and scannable.
In general, instead of dragging in PDFs, and powerpoint presentation as an attachment, you get, a bit like Windows onenote the possibility to import the printout.
You actually get a real choice. I'm really sure that this would help a lot of people.
Now you have to print the page as jpg and import it one by one (to keep the normal sequence). Not handy, this day and age if you have powerpoints of more then 100 slides...
