I'm currently working on a Pathfinder Character Manager but struggle to find the time for it.
I try to spent at least 3 evenings out of my week on it.
I'm good on the technical side but what I really like is a good design, if yous want some JSON blobs I could upload what I have somewhere if you like?
So far I've got some json files for equipment, feats, naturalDamage, races, sizeModifiers, spells and traits.
