Ok, so here's a suggestion that shouldn't be too difficult to implement. The original psionics rules in the psionics handbook function almost exactly the same as non-weapon proficiencies. So how about adding a separate section to the proficiencies page for psionics? Or at the very least, give players the ability to create skill categories in the way that different types of magic spells can be separated?
I understand there is no automation mechanism for NWPs, but most powers cause effects that can't really be automated anyway.
