Microsoft’s OneNote is an incredibly useful tool for note organization, and with the advent of 2-in-1 devices, digital inking. I have personally been using the Android version with an active stylus and recently moved over to Windows, only to realize that the default pen colors and sizes are slightly different. For the sake of consistency between notes, I was interested in tweaking these settings to be reasonable similar across versions. Unfortunately, there did not appear to be any OneNote extensions or programs for accomplishing this easily.
