Just a little snapshot of the layer7 tab to tease you 
Layer7 Tab in pfSense Shaper
Development is advancing. We are still having some problems with the protocol definition but we hope to sort them out soon.
This is just a place to create what we call layer7 containers. Each container can have multiple protocols with diferent definitions. After you create a container you will be able to assign it to a firewall rule! At least this is the idea. More to come soon 
Very cool stuff guys, I’m looking forward to seeing more.
Another step towards world domination! Great work!

I’m very interested in the progress of this project. I’m looking for a way to keep bandwidth usage sane for a University dormitory. This looks promising!
