Extrude direction

there is another command that feels a bit unexpected in comparison to _extrudeCrv
_dim
entering a fixed value for the distance:

_dim
pick first point
pick second point
100 enter … to define numerically the distance for the dimension
now a mouse-click is needed to define the direction

but even more annoying:
clicking enter a second time, the command is canceled !!

please mc neel - make those direction inputs consistent !
i want the same workflow and feeling for similar input.
or at least - if a click in the viewport is needed - give some visual feedback.

thanks

kind regards

Tom
