I'll be posting them later.
Currently working on a partial easily-missed list. Basically this is the topic for "what do you think should be added to the list", while future topics will describe in detail.
AoE defense is an error in the table: It lists you suffer a -2 on Defense Tests, but that is from a previous version. You do NOT get a Defense Test against AoE, so there is no -2. However, in Run&Gun there is an Interrupt Action that lets you run away from them instead.
Recoil house rules come in 2 flavors. One resets to SR4's system, where it doesn't accumulate at all. The other one requires you to not fire for an entire Action Phase (or for 2 Simple Actions) to reset recoil. This makes how many rounds you fire a more tactical choice, and has a balance effect on BF/FA vs Single Shot and Semi-Automatic weapons. The recoil debate also has severe consequences on the balance of Automatics vs Longarms.
