New: "Onion skin" highlighting of souce code
Code Climate now handles smells in red in the source code listings on the class details page. I call this "onion skin" view:
If there are no issues with a line of code, it shows as green. Complex methods, duplication and classes that are complex overall are highlighted in red. If the line of code has multiple issues (e.g. duplication within an overall complex class), the red will be darker to signify the number of problems.
