It seems a small thing - just one extra tap after opening up the NN app as it always defaults to display full list on notes, but my notes all go in notebooks, and that's always where I want to go first. But over time, the net positive of removing that friction, which feels unnecessary, would be massive.
Seem like a simple and easy way to get a huge boost in the fluidity of the mobile UX, especially for an app that is so fluid and great to use in so many other ways. ❤️
