Use case or problem
I often need to paste very large (up to a full page in size) diagrams from my textbooks into my notes. When they’re small enough not to crowd out the rest of the material, they’re too small to read. When they’re large enough to read, they push all the notes down.
Make the image expand to its full size when clicked with the mouse, but retract to the user-specified size (with the pipe) after clicking it again.
Current workaround (optional)
Currently I put the full-size image in a nested, collapsible bullet point. This doesn’t work too well, because it still crowds things out, and also every time I edit the note it un-collapses the nesting in the preview window, which is often annoying.
