Thrust-like

F - extend/retract clamp - cannot be retracted while clamp is open
G - open/close clamp - cannot be opened while retracted.
Slider- thruster strength multiplier.

To launch: extend clamp, then open.
To grab: Align target grip with blue marker, close clamp and retract for stability/secure connection.

Those old enough may remember Thrust & Thrust II, where you had to go and collect cargo on the end of a tractor beam, behaving like a live load.

This is my ode to Thrust.
