In most games, when i open the Diplomacy screen to trade resources, i expect to see a slider or a box to enter an amount to give to said player.  But in Sins of a Solar Empire, i have to hit a button x times to pass my well earned resources away at interverals of 100.  I can understand why it is like this in single player games, due to the missions, but in multiplayer this does not work.  When i pass resources on to another player, i have to trust them to pass resources back.  When i trade with the pirats, i can't backstab them but players are free to forget to give resources back.  I think this is an annoying issues and should be fixed in a future update.
