Hi lo-fi, if you would like more help, I would be happy to help. I don't know much about unity plugins, but I am eager to learn. Maybe having someone who is "greener" could help with ideas and code, whenever I get stuck on a project at work, I like to bounce ideas off of someone who doesn't know as much about the project. I find that, since they have never been told what "cant' be done, they tend to come up with ideas that I wouldn't think of.
And if you need a break, take one, I understand how it feels to be so fed up with something that you want to quit.
I hope all goes well for you, whether you continue on this or move on.
