Adding Atmosphere

[Utopastoo]

You should add something like an "Add Atmosphere" button which enables climate simulation for that object; because currently the only way to create a planet with a climate is to take Earth or Mars and mess it up a bunch to make your own planet (with a climate!).

Also: importing depthmaps to create custom terrain on a planet!

I think this has been around since at least Alpha 10. Under the Temperature tab, there are several options for editing atmosphere. Hope this helped.
