Origin arrows snaping as verts to other verts (for objects and bones)

Right now is very hard to set Origin in object after separation. If the local origin not spending requirements around rotation axes it need to changed, but how to.. - I think is not possible in good workflow.

The idea is to give Origin arrows a type of verts to easy snap arrow edge to object edge eg. from begin to end the origin on similar orientation that have object.

By this user can easy reach option to rotate object after new re-setting of origin in transform process to affect only origin, and after turn off affect of origin rotation of object can be correctly done by new orientation regarding origin.

There is a CAD transform addon, can offer origin rotation, but is far for setting each type of axes - don't know why, but is nearest solution that can have some changes to resolve problem, eg. before starting changes around origin, then axes by keys x,y,z can be selected to snap point right to the needed edges and verts.

If object is oriented outside Rotation 0,0,0 on x,y,z then each option as global, local is hard to set right rotation on object or this same bone if applied. By this also bones must have this option to operate origin.

If exist some other tools that I'm not know about, let me know how users doing origin transformation in good way.
