For what it's worth, I don't think my device has ever crashed. I wonder if there is a memory overflow bug such that different types of usage could lead to different crash frequencies?

I agree it would be nice to turn off quick sheets for those who don't use it. For me, I love quicksheets. I often want to just grab the device, jot something down immediately, and put it away. Sure I could create a 'notes' file and put it somewhere obvious, but quicksheets reduces the time and effort for these quick notes.
