diplomacy interface improvements

A few simple additions would make diplomacy with the AI players a lot more manageable and fun. These mostly just reduce the need to open the diplomatic interface over and over, just to see where the other players stand.

1. On the F2 screen, where the civs are listed together with whether you have a trade route with them, there's a symbol next to each civ for what resource(s), if any, they have for trade. (This is only displayed for civs you can trade with, not ones that you can't currently trade with; it would be nice to show it for both, so you know who you need to hook up to, but that's a separate issue.) It would be simple to add a symbol (e.g., a lightbulb) next to a civ if it has a tech for trade that you don't know. This is information you can get by opening the diplomatic screen; this would just be a shortcut. If it has two different techs it could trade to you, display two lightbulbs.

2. Another great thing would be a way to "offer" something for sale and see who will give what for it. I'd like to be able to select a technology or resource, and click on a "What am I offered?" button. This would just display what every civ will give me for that, the same as if I went to the diplomatic screen for that civ and clicked on "What will you give me for XXX?" but they will all be listed together on one screen. Then I could click on any one to accept that deal. But just knowing who wants what I have, and roughly what they will give for it, would be a huge win.

I'd like to see an indication of the colour of the civ that has suddenly started diplomacy with me (like colour the border of the leader pic). I have to admit sometimes I only remember who is who by colour at early times in the game. To remind myself I read the city names, but would rather see the civ colour.

Your first idea would be great and sounds easy to implement. There should of course only be lightbulbs representing techs you can actually buy (the ones for which you have the prerequisite techs). This would greatly reduce micromanagement.

Your second idea sounds great too and would also reduce micromanagement but is probably more difficult to implement.

I hope there is still time to implement this.

I hate it when I offer something (tech, resource, map) and the AI offers me 80 gold. I have to manually open and reopen the lump sum screen to ask for more (or less). A simple "+1" , "+5", "+10", "-1", "-5","-10" button saves me a lot of annoying 'click on amount and type in new amount' actions.
