From the new interview, I gather that Dark Avatar will have tons of new jewelry. That, in and of itself, justifies the money I spent (or will spend) preordering the expansion. Ship design is definitely one of the big seeling points of the game for me. I had a few suggestions:
1) It would be great if parts could be sortable into categories based on shape, say:
a) flat things, wings and struts;

blocky things, like boxes, short towers, and spheres;
c) long thin things, like antennae, prongs, and tubes;
d) lumpy things, like the "mushroom" fins;
e) wicked cool funky stuff, like the fork-thing;
f) true jewelry, like the lights and the race icons;
2) It would be great to have another category with recently used jewelry, to save the hunting;
3) It would be nice to be able to override the racial color scheme for particular ship designs. This would permit special funky "elite" squadrons, etc.;
More coming up...
