Two more items to go on my wishlist (seeing as a good portion of mine seem to be in the game from what I can tell).
The ability to assign a character to be the admiral or general of a task force. This would work exactly the same way as Rebellion. You can assign a character to a ship and they will provide a bonus that could give you a tactical edge you might need against a superior enemy.
A long with a scenario editor, a campaign editor is also a must. This would basically allow people to create their own campaign setup. So if I wanted I could create a campaign around the Thrawn Trilogy etc.
