Livereload CSS and images without browser refresh

Not sure if this is as-designed or not, but it's stated in the documentation that *Hugo may not be the first static site generator to utilize live reload technology, but it’s the first to do it right* so I create this issue:

* I'm used to LiveReload in Grunt (grunt-contrib-watch), and when I make changes to CSS - it will inject the changes without making a reload of the page.
* In Hugo evey change forces a browser refresh
* I have confirmed that the only change in /public is the CSS file I changed.

If your normal work flow is writing articles, then this isn't a real issue - but for pixel tweeking in CSS there is a big difference.
