I use dry erase magnets on my whiteboard to manage projects for my team. The dry erase magnets are thin though so it takes some scraping with your fingernail to pull them off. I reworked SH's Thin Layers Scraper to add a place to glue a ½" by 1/8" (12.75 mm x 3 mm) magnet so I can place it on the whiteboard, and use it to get under those thin magnets.
