This extension is inspired by IntelliSense for CSS class names in HTML. I want to support less or scss but that just support css. By the way I want to learn how to write a vscode extension. It's just used for me, so it may be unstable.
Features
Gives you autocompletion for less class definitions that can be found in your workspace
Auto re-cache when your .less file is saved
Command to manually re-cache the class definitions used in the autocompletion
