I seriously thought about adopting Notebooks into my workflow. The iOS app is really nice, but I find the Mac app to be an odd user experience. My main gripe is having no option to turn off the silly paper background. UX details like that really bother me when using an app as much as I would an app like Notebooks. I’m heavily looking at KeepIt alternatively, but I’m bummed it doesn’t seem to natively support Markdown file creation inside the app.
