I think you should add an option to fit covers to document sizes. I mean that I for example bought a few sets of covers for goodnotes app and even though they all should be in a4 format I just couldn’t get them to fit the regular template size or even the a4 template size. It’s either smaller or bigger than the notebook pages. There is always a difference in size. If Etsy has such a big market for digital content for your app and also different other sites I think you should add an option to make the notebook cover and pages same size.its simply a piety I try so hard to make my uni notebooks pretty and customized but I barely can get a cover to fit right.
