It would be nice to have a pause, that would allow you to move the camera around so you can checkout the landscape and have a chance to plan your colony.
here is what i do when i plan a base:
1. save the game
2. turn on Yellow Alert, so bots/colonist won't try to build anything
3. pan and zoom however you want
4. place as much structures as you want, you can place them even if you do not have the resources
5. if you are satisfied with the design, remember it, or better yet take a screenshot
6. reload the game like nothing happened
7. slowly build your plan
What do you think?
