Right.
I'm using Brackets (Adobe's open source code editor) more now. In particular, I use LESS with LESS Mixins & variables in Brackets to produce my CSS code. The autoCompile add-on automatically minifies my CSS code when I save the LESS files. If I need to revisit the CSS code later, I open the LESS files and not the CSS file. You might want to give Brackets a try. It's an awesome code editor.
