Personally, I don't rate the current aid all functionality that innovative or game-changing. You should be able to select any or all of guild - hood - friends and have them all aided at the same time in the background. I don't need to know when its done. There's far too many pop up notifications in the game anyway. I don't need to know I've just got X coins from aiding a few people.
Speeding up negotiations would be far more useful. Get rid of a few "OK" pop up boxes and speed up the animations.
Get rid of the pop up box that tells you how many seconds are left until your building is constructed. Just build the darn thing. I'll know when its done. I don't need a countdown.
