I'd love to see a Joomla! plugin ( (it's not dead!) that my marketing team was able to use and not have to submit tickets for every new tracking idea they come up with. Right now any request for tracking has to go through quite the process and pull devs away from other tasks just to implement which is a little tedious in Joomla! without hardcoding, etc.
There are some GA extensions that work great and would like to see something similar.
