I dont use hyperdrive I's but they are not aligned by default when placing them on ships. (yes all the position sliders are at the default position.)
A few of the extra ship jewelry textures are not done.
Make trade worth more. And not for just making ai love you just before you beat them to death!
One other thing with the different Trade techs. For Advanced Trade lets your Freighters travel at say 1/3 to 1/2 their real speed when on a trade route. And Master Trade lets your Freighters travel at 2/3 to 3/4 their true speed on trade routes.
Maybe with Master Trade you can put 2 moduales on your Freighter and double your money. Just an idea.
The Altarian/Drath moral structure (I can't remember its name right now but the first one 75% to morale) its image doesn't show up after the pop up message that its complete and when selecting it on worlds too.
Arcean Empire. They really need a little boost or something. Give them at least Ion engines or hell at the most Impulse I tech. They are to slow and you can steal any advantage from them.
In the option menu set all Starbases to a default option to auto improve(ie place a new base and then tell each and everyone that I want them to auto upgrade when constructor arrives.)
Constructors should be used up when building a Starbase but not when upgrading a Starbase. Make them like miners so I dont have to build so many.
Some ai's dont expand as well, like the Terrans are great at it. I want more blobs!
I'll try to think of more...
