not an issue just suggestions!

this project is great, thank you very much for your efforts, I have some suggestions though

• enabling code splitting, maybe grunt has to be replaced with web-pack.
• add auto prefixer for css/sass.
• java-script linting should be separated task by example: grunt run linting.
• use eslinter instead of jshint. I recommend to integrate it with IDE

• use postcss instead of sass. there is nothing wrong with sass, any way have a look at http://postcss.org/
• add support for ecma6.
