7. Ships designs appear unlocked by unrelated research. I believe this is caused because I traded for some techs from the AI.

8. Sometimes when selecting Starbases in Set Shipyard Destination it doesn't work, I hear the click, the selection lights up, but nothing.

9. Had a CTD when going to the Treaties screen, ticket submitted #HHN-302-54493.

what i would like to see is about 6-12 or so improvements that can only be built once per galaxy and they get adjacency bonus's from empty tiles around them

the empty tiles would also provide bonus's by type 

Sandy beaches resort - +1 for every empty tile,-1 if tile occupied, +2 if empty tile is coastline or water

olympus mons ski lodge- +1 for every empty tile,-1 if tile occupied, +2 if tile is mountainous

survivalists challenge hunting lodge - +1 for every empty tile,-1 if tile occupied, +2 if tile contains forest's

special tile

the village - this rural village blends in so seamlessly its hard to imagine its actually a tourist trap 

must be placed adjacent to a tourism building, +5 adjacency bonus to tourism building (this bonus is only applied once to any tourism building) (this bonus ignores the -1 for occupied tiles adjacent to tourism buildings)

11. I'd like a cancel all ongoing projects button, this is for colony projects.

12. Think I mentioned this before, but doesn't hurt to repeat it again. I want shipyards to have a visible ZOC like starbases.

13. After a tech is researched there is no way to read it's long description.

14. UP headquarters bonus is applied to all planets, not just the capital.

15. I request the tactical view colors for the research and culture relics be slights changed, since they are too similar to those of the Terrans and Altarians.

16. It would be nice for somewhere to be displayed how many Ascension nodes, strategic resources, relics I own and how much I get per turn.

17. When selecting the sponsor planet for a freighter I'd like it if there was a tooltip with the planet's info when the pointer hovers over it.

18. Problem with the trade route value display. It says 75.6 is both the raw value and the trade route value. So either the bonuses aren't applied or the raw value is displayed wrong.

19. All my trade routes are there, but to whom does that line going from the top to the bottom belong to? Also it would be nice that when selecting a trade route it would be highlighted on the Trade Route Map.

I have to check them in more detail, it's kind of odd that the Drengi one has the highest value, since I remember it has the least planet income.

20. I'd like a UP proposal to kick a member out of the UP, also one to welcome them back in.

21. I've been thinking of a new treaty: Vassal Treaty. A civ that becomes a Vassal can not declare war on the civ it is a vassal of, trade, declare war or have treaties with outside civs. If it is a major it would behave like a minor and not build colony ships, but would colonize with colony ships and use planets gifted to it. Its planets would not culture flip to its vassal lord, but would to outside civilizations. Minors would be more willing to become vassals, but a major might have to suffer a crushing defeat in a war, or be on the verge of extinction. Vassal civs would no longer count for Conquest or Diplomacy victories. And if you made all the major civs in your vassals it would be counted as a Conquest victory. And they would not have place on the UP council.

This sometimes occurs also with planets you culture flip; the ring around them is in the old owner's color.

24. Sometimes when using the mouse wheel to scroll in menus the list will get stuck to my cursor; meaning the wheel no longer works and I go up and down the list according to how I move my mouse.  It stops when I click the scroll bar.

25. Are Death Furnaces supposed to be one per empire?  When I finished my first one they disappeared from the list on all my other colonies.  However, other furnaces I had queued were built.  I did the same thing with the pragmatic equivalent building.  I hope they're not supposed to be one per planet; on a huge map that's a pretty sad bonus.

26. The game still occasionally freezes on me the way it did on patch .50.  It's pretty difficult to replicate, but seems to happen most often when I'm dragging the map around after doing something that taxes the computer a bit, like loading the game.

As far as vassalage vs specialised tech trees and units. I think the overlord should get the better of the current techs or all the researched techs of both factions. Optiionally all specialised research paths from the protectorate should be available to the other faction. The techs that are the same but are at an easier research path should become available. Units are similiarily handled. The specialised units of the protectorate should now become available or only what is better. This could include one per planet or wonders. The specialised units that are available in both tech trees that havent been researched yet. Could optionally be handled this way. 

You might want to build the constructor without some of the support modules it has.  Once you get +20% Storage Capacity, you can fit a Construction Module on an empty Tiny hull, greatly reducing the cost.  With the cost-reduction techs, I was able to get the basic constructor cost all the way down to 19.
