...in Missions we have no choice but to deal with the poor editing and disorganised structure. Some in our local group took the initiative to create "cheat sheets" and playing aids such as ones for spirits, matrix actions, and combat actions/options to minimise having to plough through two or three books to find things during play.
I've been using Chummer instead of the standard character sheet as it provides more details, like weapon attributes, skills/pools, armour, vehicles, etc and doesn't run out of space for gear (I have yet to see a "out of the box" RPG character sheet that provides enough room for gear/supplies). It's not the best as it does have a few odd traits, but it does help organise the character better. Hero Lab actually gives a bit more information and is pretty accurate, but it is expensive and generally you need a tablet or notebook computer for your character to access those functions.
