|Mode:||Object Mode, Edit Mode and Pose Mode|
When bones are selected (hence in Edit Mode and Pose Mode), their properties are shown in the Bone tab of the Properties editor. This shows different panels used to control features of each selected bone; the panels change depending on which mode you are working in.
|Mode:||Edit Mode and Pose Mode|
When in Edit Mode you can use this panel to control position and roll of individual bones. Whereas in Pose Mode you can only set location for the main bone, and you can now set rotation and scale.
In addition, in Pose Mode it is possible to restrict changes in position, rotation and scale by axis on each bone in the armature.
This panel controls the way a bone or set of bones behave when linked in an inverse kinematic chain.
