@Imhotep:
The current tech alert is pretty slim on details:
New tech(s) to trade: Saladin, Montezuma, Bozo the Clown
Here's the opposite end of the spectrum:
Stalin will trade Bicycling, Mockery
Isabella won't trade Gambling
Yogi Bear has acquired Park Ranger Evasion
The second one is a new alert, telling you that Isabella is no longer willing to trade a tech that she was willing to trade earlier.
The third one isn't even related to trading, but it is information readily available by hitting F4 every turn.
Of course you won't be told about techs that you cannot research yourself, same as on the trade screen. I'm not actually in favor of this -- it's rarely that important save for a few key military techs, and in the one in a billion chance they'll trade it immediately, you'll be told about it anyway. I put it here just to be complete.
I for one like that each AI gets a separate alert rather than grouping them all together. As well, the point of the alerts is to alleviate the need to open the screens.
@Ruff: While it can be made optional, there is a point where we can have too many options. We don't want the options screen to become unusable. I don't know if this crosses that line, though.
Also, I'll take a look at the bug you mentioned.
If we can arrive at a consensus, I'll gladly add this feature.
