HUD Colors
Okay okay, pretty much everyone already knows about Arkku, right? And even I use it. But there's one big, almost monsterous disadvantage to it that could be solved with a simple suggestion:
Frontier, please make our primary HUD color customizable in-game.
The problem I'm referring to, of course, is that when you modify RGB values in Arkku, it changes the RGB values for everything. And while it is possible to set it up to be the color you want while still being able to distinguish different markers on your sensors and such, it is extremely difficult, and may not be exactly what you're looking for.
Having a set of RGB sliders implimented by Frontier that modify EXCLUSIVELY the base HUD color (what is typically orange), and leaves everything else, inclusing your combat rank, their default color value would be a big, monumentous step forward from the current system. Not to mention get rid of a lot of headaches.
