Thank you very much for your feedback!
I absolutely agree with you! This is one of the main reasons why I created SuperSettings.
I am aware of EditorConfig and I think the greatest strength of it is the ability to configure different editors with one cross-editor configuration file. However, it's greatest strength is also a weakness since it handles, like you correctly said, only general style settings. For example, an important thing for me was the ability to configure the rulers in Sublime Text, which EditorConfig can't do. SuperSettings allows you to configure any Sublime Text setting, so you can, for example, have different color themes for different folders.
