Templates separated into sections for different playstyles mayhaps? Or rather not separated but given reccommendations for such. Maybe as part of the indexing.
"Over here we have our arcane caster friendly models.*
While over here you can find some more divine focused models.*
And off in that corner are your pouncers.
That shelf is full of glomp friendly types, from your grapplers(Improved Grabs, ect) to your heavy eaters(Swallow Whole, ect) to your lazy couch potatoes(Crush or whatever)."
*cough*Edit: And by that I don't mean simply templates that grant spell like abilities or what not, but rather ones that can advance/stack with spellcasting of other classes one might have. Like, off the top of my head, there is that Dragonspawn template from Dragonlance that progresses and/or stacks with previous/future sorcerer levels to determine spell stuffs.
