The Joint Origin dialog box provides the capacity to select the Type of Origin- "Simple" or "Between two faces"; making the second selection presently requires clicking on the Type pull-down menu, drawing down until "Between" is selected, then clicking. Not such a big deal if performing this operation only once- but when confronted by a large number of components, the process is onerous.
This selection may be accomplished with greater ease by replacing the pull-down menu with simple two-state radial buttons- one click between the two choices, no drawing, aiming, or additional clicks required. Those required to frequently use the interface will appreciate the change.
