I'm in favor of this, especially since spotting doesn't always work very well. There are times when ships are seemingly just NEAR a cloud, extremely visible, not shrouded at all, and I can't spot them, so I assume they're friendly (especially because the lighting often makes it impossible to tell the difference between red and blue flags). I mean, I guess there's the map, but when things are hectic it would be cool to just be able to directly look at the ship and know it's friendly rather than spamclicking with spyglass equipped until the spot finally works (or doesn't).
Also, I have an impaired ability to mentally spatially rotate things, so I can have a hard time using the map to tell if I'm pointed at a friendly or an enemy. Even harder if there are two ships in close proximity.
