A nice feature request would be for alliances leaders to request a rematch at the end of war. If both alliances opt to rematch, then they automatically match and war again. Perhaps a two out of three limit before another random search would be fun.
It would be great to select an area of a base to move more than one piece at a time, or select all and move. If I want to shift my base over to rearrange a few things, I basically have to rebuild it.
