The Kineticist wild talents badly need lists which order them by element type and level, rather than alphabetically (ultimately I suppose this is no different than the way spells are listed, but without a few decades of experience to draw from it's pretty darn hard to quickly locate, say, all powers available to a 6th level Terrakineticist). Obviously that will come in the full product, but it would have been helpful during the play test from a pure usability standpoint.
These lists are actually there, at least for Wild Talents. In each element's section, the last block is the element-specific wild talents. The last paragraph before the list of Wild Talents, is the universal list, available to all kineticists.
