The engineering pad provided works great on pixelbook but my new primary note-taking platform is the Lenovo Duet with a 10.1" screen, and the engineering pad just doesn't fit. The A5 notepads are close enough, but could also be a tad bigger than that.

Actually, with further experimentation, I've found that setting the default zoom to about 70% is a pretty good workaround for this and most of the backgrounds. Setting to fit width works but makes them a little too small.
