One of the things that takes waaay to much of my time is when I have to pick a specialist tech and, being the power gamer I am, I have to manually search every single Ai. I have to check every AI I have meet to see what techs they already know so I can trade for the others. Likewise its really annoying when there is a normal tech I need ASAP and I need to spend ages searching to see who has the tech im looking for. This is especially difficult in multi player when there is limited times between turns to keep the game flowing. To me there is no reason this shouldn't be added in the main game, we already have the ability to check the techs of each AI one by one, the only change this would do is to make it so much easier and efficient. The AI is able to instantly check all techs of the other races why cant the player?
Functionality
-The Hover tool tip displays the total number of available AI that have the tech. 'Available Traders'
-When you click on the tech the right display lists the Available Traders in drop down menus, separated by general attitude towards you 
-Of course if you dont know of the AI yet they are not listed.
-If you are at war with the AI they are also not listed.
-It will also show minor AI
-The "willing to speak to you" icon is shown
-Ideally I would love for it to show you "X-turns to they will speak to you again" but that isnt even in the main game yet.
-You can click on the name and it will automatically take you to the races trade screen
-You can hover over there names to get the hover window showing the + and - info of the race
To me this is a simple UI change that has huge benefits both in functionality, reduced turn time due to not having wait waste so long searching, and as I said its not giving the player any benefits the AI dont already have.
