I often find myself comparing the HTML and CSS of two similar web pages by having two web inspectors open side by side. Wouldn’t it be cool if there was a DiffPlug browser plugin that allowed you to diff this stuff? There’s likely to be a huge market for this too.
Thanks for the suggestion, Todd! Adding a browser plugin is a great idea.
In the meantime, you can get a similar effect using DiffPlug’s web filesystem. It’s a lot less convenient than a browser plugin for sure, but it works!
