Pros
Pro Improves Sublime Text's user interface
The theme cleans up the interface so that all elements in the UI are easier to find without being distracting. The icons for each file type clearly define what the file is so there's no having to look too closely at file extensions.
The color scheme choices (such as Oceanic Next Dark) in particular work well to distinguish functions, classes, keywords, properties, values, etc. for various languages.
