psionics – What are other uses of Power Points in Pathfinder, especially for non-protesters?

I know this has been requested for D & D 3.0 and 3.5, but listen to me please because it concerns Pathfinder.

I find that PP is used to feed and modify psionic powers and that the psionic focus no longer requires a reserve of PP, as well as new uses; like using psionic talents without increased PP.

Wild Talent wins the 2 PP reserve of the user (and I think you can add a bonus for a high Int) and counts as a psionic creature.

With the capabilities and psionic powers of the majority of Pathfinder related to Psionic or PP Focus uses for protesters, where else can the PP be used by non-protesters?
