Text editors are a bit like religions. There are many, and the features, but similar, differ from one editor to the next, and are used differently by each user, according to taste, experience and needs. If the mantra does not improve without change, it's true and I think it's important to check out new offers.
My Mac is graced with a number of text editors; Some free, some not, some like old and comfortable friends from last century, something new but worthy to mention. HueNote falls into the last category because it acts as a text editor, but also a note app, and shows what you write or code in a unique way. Parallel more notes.
Here is a visual example.
HueNote handles three types of codes for easy identification; brand, color and keywords. The app is iCloud Drive knowledgeable so you can save documents online and make them available to other Macs. And it contains new OS X-based details, including full screen mode (very convenient with multiple work areas open), and of course auto storage.
HueNote is new and something of a superior taste, but the more workspaces within a single app display have advantages. However, support is in Japanese, but the Mac App Store also has a free version to try first. Remember, nothing is improved without change.
