As we all know, jewlry is used for decoration when designing ships. One thing that has irked me, however,is that I can't put nose art on my ships. There are many possibilities:

1. Squadron Insingnia

There are tone of possibilities: shark's mouths, (a nod to us Flying Tigers fans,) marks of real-world air forces, (I imagine that a Luftwaffe cross would look great on my F-10s.)

2. Civ logos

Sorry, but I really hate the logo jewlry the game provides. Just think how badass a huge Terran Empire logo would look on the bow of a dreadnaught headed for a Drengin cruiser.  

3. Different skins (not really jewlry, but hear me out.)

There are a lot of possibilities here: 'Battle Scarred': a beat-up-looking skin, with chipped paint, burn marks and maybe rust.

'Veteran': the fusalage is full of logos of other civs, and 'ACE' is painted on the wings if it is a fighter.

'Mercenary': Can't think of a paint job, but some kind of logo (ya know, for the merc company you contacted,) would be nice.

'Experimental': Normal skin, except 'TEST' or 'EXPERIMENTAL' is painted on the wings.

well, there's my two cents, in all thier glory!
