I found another discussion talking about Font Awesome being removed and a suggestion for the future to have a standard location for user add on libraries and assets. 

What is the best location to store these libraries right now?

Is there any folder within the laserfiche forms installation that you generally try to avoid/changing? i.e. if we create a subfolder under js-src for our plugin, will that path change/break/get erased when new versions come out and we install over top of it?
