Subject: A nice character modeling time-saver:

In WeightPaint mode, pose-mode armatures now allow selecting Bones, but
without making the Armature object active.
Selecting a Bone then results in selecting the associated vertexgroup. :)

Little quirk; all armatures with posemode then draw selectable...
