The white server connection status display is so out of place its distracting, at least match the font colour to the flight deck colour scheme, and dim it a bit.
Do you mean the one on the main menu?
He might be writing about the comms status (Rx & Tx). That can be seen in the bottom LH side of the game screen. You can toggle it with Ctrl + B, on a PC.
Ah, I didn't even know about that as an option... and I've been playing since late beta.
One of the things you can use it for is to see if there are real players in the next system you are jumping in to. The Rx goes way up as the game sends the info.
There is also Ctrl + F for frame rate display.
Quite useful... especially as I play solely in Open.
