(Enhancement) Please add source maps for minified code #1902
http://www.html5rocks.com/en/tutorials/developertools/sourcemaps/ gives a quick overview for the uninitiated.
Essentially, usage of source maps should aid in the debugging efforts of production code as one would no longer have to switch back to highcharts.src.js just to track down errors.
I'd like to add my support for this enhancement. Given that the issue has been open for nearly two years, I'm not optimistic, but hey, maybe it just got lost in the shuffle?
Auto generating a sourcemap for the minified code should be as simple as passing a flag to Closure Compiler...
