I'm going to start my foray into the fora by bringing up a complicated subject. You're welcome.
A lot of characters in the Star Wars universe are defined by their possessions. The most obvious example is Han Solo — he had a distinctive blaster, along with his ship. Every Jedi and Sith has a custom-made lightsaber, or has borrowed a unique model from someone else. While other characters just use whatever incidental items they pick up as needed, the rest rely on gear that stands out and is a part of them.
Please don't ignore this. It adds a lot to a character's image when he has a reason to specify the type of blaster in his hand — it's one thing for a smuggler to have a heavy blaster pistol, but it carries a lot more weight when he goes through the trouble to say he has a DT-57.
I'd like to see an add-on book that deals exclusively with the gear chapter. This may include minor variations on a weapon's stats for certain models (the DT-57, for instance, might have a slightly better crit rating and require more negative dice to run out of ammo). A lot more illustrations would be a must; half the work's already been done there, thanks to Wookieepedia.
In addition, this would be a prime opportunity to account for different eras of play. The biggest difference is in the Old Republic era — at the beginning of that period, the ubiquitous blaster was an experimental piece of tech, limited to military units. Most people carried street-legal pulse-wave pistols, or sonic pistols that had the advantage of bypassing lightsaber blocking.
The previous Star Wars RPG had a sourcebook specifically for that period, and even brought up things like this, but didn't have any rules to back it up. Bugged me the whole time.
