As the Perk list is growing... may I suggest some way of sorting or filtering?
Melee, ranged, misc.
Melee - Unarmed, sharp, blunt
Ranged - pistol, sub, precision, shotty, assault
I'm sure misc can be filtered into various things, but unless there are a ton of them, why bother.
But, I definitely find it a bit of a mess when I'm wanting to buy perks. I'll be on an unarmed melee character and having to click on a bunch of perks, then looking through the unavailable ones, trying to find specific unarmed perks. Then I go through the same on my Assault rifle character and so on.
When there weren't that many perks to start with, it really wasn't a thing. Now the list is growing out of hand (which is a good thing).
Being able to find what you want would be nice.
