Internalize for Google Analytics - Send a Custom Dimension hit at the click of a button. This tool is intended to annotate traffic in a certain way, letting you filter it out or process it in any way you choose

Feel free to send me any feedback relating to the tools. I don’t do extensive testing, nor are the tools especially optimized performance-wise. These are issues I would love to tackle had I more time, but I’m really grateful for any ideas, feedback, or criticism you might want to throw my way.
