So...not sure if this occurs only on smaller screens(playing fullscreen on a laptop with 1366x768 resolution) but as you collect perks(both by leveling and those you get in events such as Top, x Addict etc.) I reach a point I literally can't see all of them.  Honestly no clue if I'm the only one with the problem or all who play on that resolution have it.

Though, if it's the second one...and if we do get more perks as we get more story(which I honestly believe we will as the game's in Alpha still) maybe that portion of the character tab could be modified to be like the inventory tab has so you could scroll up/down the list with the arrows?
