Images outside of page borders

I often screenshot parts of text/other notes and paste it into the document to copy the text. However, I often have to scroll to see what I’m copying, especially when im writing close to the bottom of the page. It would be super cool to be able to add images just on the outside of the canvas (like next to the page) to improve the experience. Currently, the images disappear as soon as they’re off the page.

To see what I mean, compare this to PowerPoint. Images can be added to the outside of the slide to be kept in the document without being visible when presenting or for editing purposes without disappearing into the void.
