Has small guns, sneak, and energy weapons tagged.
She will level when you do.
She will heal herself with stimpaks outside of combat. She will not fully heal like the regular companions, so keep her well supplied with healing. She should heal completely when you rest though.
You can tell her to wait in an area (she'll walk around, use the furniture, etc.) or stay in one spot (guard this spot).
She will stay sneaking if you talk to her while you're sneaking. Looking up at Charon while crouched down was getting annoying.
You can adjust her fighting tactics (melee or ranged), how close or far away she follows, and how confident she is (brave or cautious).
She'll currently comments on all of the MQ starting with finding your dad, disarming the bomb in Megaton, and doing all of Moira's Wasteland Survival Guide quests.
I plan on her having her own quest, but I haven't decided how I'll handle the DLCs yet.
Here are a couple of screenshots I took of her and her new hair:
