Ok, where to start?
@Brian was asking about Chat in the improving your own WPO thread here:
A couple of suggestions or ideas came out of that.
#1: Create an “module/application wide” spot where you can put footer code.
For example the “IDX search” is a module, the Blogs are a module, “details pages” are a module.
This way you could drop in code like javascript on “just” those pages.
The use case here is to get more granular with how you use elements like pixels or chat. You can keep your fast pages fast, but high value conversation pages you can test things like chat etc.
Seems like a quick win, easy to code. 
Thoughts? Helpful?
