I've had addons for a while now:
BetterVendorPrice
ClassicCodex (Disabled, but downloaded in case Questie goes *boink*, since I refuse to risk a relog in the first hours post-launch)
OutOfRange (See above, this time for tullaRange)
Prat-3.0
Questie
RealMobHealth
ShadowedUnitFrames
tullaRange (BFA mod, but works in Classic)
