More things I'd like to see:
Magazine & power pack weights for slug and energy weapons.
Include art of power packs for laser pistols, carbines, and rifles.
Law Level ratings in the entries for every armour so you don't have to extrapolate from the law level table in the core rulebook.
More complete table of contents (some chapters were missing from the previous published edition).
More complete rules for Smart weapons (e.g., how to they interact with a target that's not wearing armor at all?), and software for weapons that have integrated computers.
Bladed weapons: make Chaindrive, Static, Monoblade, Psi, and Stealth options that can be applied to any blade (or some blades, in the same way that ammunition types can be applied to specific classes of slug and heavy weapons), instead of separate weapons? Or at least add more options: Static and Monoblade daggers at least.
Fix the range on the Cartridge Pistol -- seems like it should be much shorter. 5 maybe?
Clarify what types of special ammunition can be used in Gauss weapons -- none? AP only? Doesn't seem like every pistol/rifle ammo would be usable in such weapons.
Make weapon art match item description/traits, e.g.: ACR, Heavy ACR, Gauss Rifle are listed as including scopes, but don't appear to have them, Big Game Rifle appears to have one but it's not listed as a Trait.
