Tension Software (www.tensionsoftware.com) has revved Notelist, a macOS app for manning notes and storing them in a data free format, to version 4.8. It’s a maintenance upgrade with bug fixes and performance tweaks.
In Notelist any note has an assigned category, where each category has a distinctive color and label. Categories are editable, and the user can create and manage how many categories he needs inside any document and apply them to notes.
Notelist requires macOS 10.10 or higher. It costs $9.99 and is available at the Tension Software website and the Mac App Store.
