Bartender3 for buttons. Discord Unit Frames hacked for 2.0 with a theme that I cooked up myself. ChatMOD, eCastingBar, SimpleMinimap and tons of other small addons. Best finds since 2.0: Rating Buster, cgCrafty and PoisonMaster3.
Pic is a little messy but I thought it was better than some random "jumping in IF" pic :)
