We really need lots of ability to sort and filter the many lists in the game. Being to see the unowned planets in a list and being able to sort this list by planet class, habitation requirement, and distance from a selected colony ship is one. Another is being able to sort the list of ships that can be built at a ship yard by hull size, type (survey, colony, combat, transport, etc.), cost, etc. is another. And there are many more examples. Finding a planet to colonize or a ship to build is frustrating without these sorts. GC2 has a lot of ways to sort and filter lists that are needed in GC3.
