I have actually some code ready that takes templates, generates forms out of them (even for offline mobile use) and uses template2pdf as backend. But explaining that in a short message is hard for me. So there is no website or good documentation on that yet. This will change very soon.
That is a fantastic use case that is easy to understand and explain.

I've tried to gimp up a nice graphic several times. I will ask a friend to help me with that. This is actually something I wanted from the beginning but never had the time/energy to finish. It just never looked good and raised more questions than it tried to answer.
Having some more pre-designed templates is also a good idea. This might not attract the right audience via search engines, but could be of real value to potential customers. (And value for non potential customers.. which is also nice.)
