Interaction without continuous user input.

Currently (unless I am mistaken) one must hold down the left mouse button to perform actions when interacting with test subjects. Releasing the button immediately cancels the action.

I propose an option to allow a click to begin the action with another click to cancel the action so that left click (or the assigned button) must not be continually held down lest the action be cancelled.

This suggestion's approval or dismissal is meant to be about simply the idea of interaction without constant user input. The following examples are just chatter on the subject that goes much further, but all would require the ability to continue an action without continuous input.

Perhaps going further holding down the button (or another input method) could allow recording of movements to be repeated until cancelled. If various parts could act independently this would also allow multiple actions if appropriate animations existed, such as fingering an anus while performing oral interaction or other combinations with reasonably feasible animation.

This topic is a rather advanced idea on the subject related to toys/machines, but I am also talking about player character actions:

Taken perhaps too ambitiously such a system would allow quite a bit of customized automation if a gambit-like system were possible with the player character as well as machines/toys. At its most simple though, this suggestion is just to offer the option to not require holding down a button at all times.
