Tweak for Donation Interface

I think that normal donations should the same as clan war donation system. When donating like in clan wars you should be able to see what troops have already been donated so there could be less donation mistakes. One should also be able to change their request without waiting 20 minutes or pay a ridiculous amount of gems. (sometimes you don't think and send the troop request. You then realize that you have requested for a lava hound when you mean to request for some wizards.) Any other thoughts or suggestions.

1) Get rich
2) Pay Supercell's ludicrous CC gem fee
3) ???
4) Profit
