Preset armies and profit on raids

This isn't an idea for a new troop, but rather an idea. I was thinking that supercell could put, where the replays are shown, how much elixar and dark elixar it costed to make the army you attacked with, and the profit you made from the raid. (Not just the money you made, but subtract the expense you made the army with). As well, the concept that you could have preset armies so with the click of a button you could have an army that you use a lot without having to go through and retrain all the troops you want. Just like you can have three preset villages for you to change at will, the same could be done with the barracks.

Thanks for reading! : )
