"send colony ship" function

[Slick]

I have a few questions about this order.

Does this order send the closest colony ship or does it choose the colonizer a different way?

Does the game check that the chosen colony ship has the right colony component for the target planet, or could it accidentally send the wrong type of colonizer?

Does the command still work if a colonizer ship (by class) is not built on a Light Cruiser or other "non-colonizer" hull?

Do people use this or colonize manually?

Slick.
