Skins are only useless if you can't see them at all, which is the case now. Sure, you get a fixed camera in the outfitting screen that shows you an authored frozen still of your ship. Yeah, well, for that we already have the FD store page, you can preview paintjobs and decals there if a still photo is enough for you.
No, I'd like to appreciate my ship and its colours and patterns from any angle, even if it's docked, thanks. Is it too much to ask? I mean, I AM TRYING TO GIVE FD MONEY HERE! PLEASE LET ME GIVE YOU MONEY!
Afaik most people buy skins so others will see them, not to see them themselves.
I'm personally against external views and prefer only in-cockpit views but I guess an external view for taking screenshots would be fine as long as your weapons are disabled whilst using it.
