Some MORE random SE:V questions

[Slick]

1) Where are the settings that control how many mines/sats are launched from a planet or kept in reserve?

2) With respect to Migration with another breathing race:
- will migration eventually undome those planets with that kind of atmosphere (i.e. or will the game keep 1M of my race on that planet)?
- if so, is there a log message that will inform me of this so I can build more facilities?

3) Why can't I get my population transports to work with the associated minister? I turned on the global minister for Pop Transports and the individual minister on that ship. The Pop Transport is of the Pop Transport design type with the default strategy of DGH.

4) I think I know there is no way to do this, but is there a way to save treaty configs so as to not have to redo them each time?
