Interesting, normally this would be moved to the "Your Announcements" section, but this is 100% art related and free so.... it shall stay.
What gave you the idea of making the unity PBR exporter? Are you planning on making a process for UE4 as well?
I'm working on a game right now called Sarah and The City of Dead, here are some links to info about it.
Basically I am doing the Unity 5 PBR workflow with the standard shader and I am working on 4-5 texture maps at any given time. It was getting to be a real pain manually updating and saving out each one individually. This tool allows me to keep all of those maps in a single PSD file, hit a single button to export them all at once...and I only have to save and work in one file! Pretty handy and a real time saver.
