I consistently use PDF's and Screen Shots in my Squid Notes. Is it possible to add an option for each page to "erase ink"? When I "Clear Page" after writing on a PDF, the ink goes away just fine, but when I "Clear Page" after writing on a screen shot, the ink and the screen shot disappear. I would like to be able to use my notes again and erasing by hand on every screen shot doesn't seem ideal.
