Separate Bone Joint Snapping from Vertex Snapping

When you're rigging is very handy to snap bones or controllers right to place in bone joints or along another bone's length or even right to another's middle. In Blender currently what does the joint snap in the Vertex Snap feature and the across length is the Edge Snap, unfortunatelly I could never find an option to snap to the center of the bone.

However, the problem with that when you're working on the rigging and need the mesh to be also active for visibility, blender won't know if it's supposed to snap to the actual mesh's vertices/edges or to bone joints/length.

I believe the best thing would be to separate mesh snapping options from bone snapping options.
