Easily copy someone's base
It would be nice if you could copy another clamate's base by the click of a button, or maybe someone you have ALREADY attacked in war or someone you have attacked in multiplayer....
or make it where you can copy anyone base, like a screenshot, except for the traps! if you go to look at an opponent in war click the new 'screenshot' button you can have that layout yourself except you would still need to set your own traps for obvious reasons
I encounter great layouts sometimes, and at TH10 there are so many buildings that it takes a while to make a new layout...
