I love this mod and find it tremendously useful (the more popular docking port alignment indicator was throwing me for a loop by wanting me to look away from the navball), but I'm having trouble understanding what exactly the red marker indicates. I understand that targeting it puts me parallel with the other docking port, and I understand how to use it by "pushing" the target indicator towards the red marker using the prograde marker, but I don't understand exactly what point in space I'm aiming at by aiming at the red marker

I'm still pretty new at the game, so I've only installed mods that give me more tools to work with instead of changing the gameplay significantly: Active Texture Management Docking Port Alignment Indicator Enhanced Navball (mostly for the ghosting on prograde/retrograde) Environmental Visual Enhancements (Clouds should really be an option in stock. I've tried uninstalling it several times but Kerbin just looks naked without it now) Kerbal Alarm Clock VOID (delta V info at the very least should be stock. It's so essential for building a decent rocket and there's no reason to have to pull up an Excel spreadsheet in the VAB) WernherChecker (found this by accident, glad I did because it keeps me from forgetting solar panels)

I'd be okay with KSP 2 if it meant a switch to a better engine. The game performs terribly with larger rockets and crashes fairly often if you use mods, at least in my experience
