Is there any way to use the tooling independently of web starter kit? Wasn't able to find a link on the site, are they just warnings you see once you start developing? Can the tooling account for JS changes and navigation between pages?
Sorry for the barrage of questions, just really hoping to find a decent tool to clean up CSS...
If it's just cleaning up CSS you're after, I would use UnCSS. Checkout grunt-uncss task or gulp-uncss to hook it up to your build process. We don't currently document using the tooling independent of the kit, but you should be able to pluck the package.json and gulpfile.js and edit per your needs. We'll try to get this documented.
