Thanks for your support, and glad you're enjoying the game!
For the time being, the minimap as it used to exist is gone. You can bring up the "not very mini" map by holding T, or by using the view you found.
The settings option you're referring to is actually talking about the bounding box of the viewport display indicator inside the minimap itself, it's not referring to the overall minimap.
Depending on feedback, we might add back in a traditional minimap at some point, but it was just too small to be useful most of the time, and something that took up a lot of screen real estate that we simply didn't have available with the larger fonts on 1024 wide monitors, so we went with this alternate solution. Other massive RTS games have done the same recently, such as SupCom not showing the minimap at all by default (and it was a pretty useless one when they did show it). With a game like this, the actual in-game zoom is something we'd prefer to emphasize, as it's just so much more functional.
Some of the other functions of the minimap, like alerting you if there are enemies on the planet, have been made more obvious in general, and have been put into the alerts box on the left side of the screen for even easier viewing.
We re-thought a lot of things with this new version.
