All bug reports and problem issues require a reduced test case. See [CSS Tricks - Reduced Test Cases](http://css-tricks.com/reduced-test-cases/) on why they _"are the absolute, ... number one way to troubleshoot bugs."_
+ Any one of the [CodePen examples](http://codepen.io/desandro/tag/isotope-docs) in [the docs](http://isotope.metafizzy.co) may be forked and used to build your reduced test case.
Reduced test cases dramatically help both you and me. They help you identify the issue at hand and understand your own code. On my side, they greatly reduce the amount of time spent resolving the issue.
