Having the ability to save base designs in the village editor, would be a nice addition to the game. You will only find the perfect base by testing out different bases. Switching between villages by just clicking on, for example, "Village 1", "Village 2", ... instead of rebuilding the entire villages over and over again would save a lot of time.
I think that's a great idea, I can't believe I haven't thought of that.. But yea, I have like 3 different lvl 7 town hall base designs and it's frustrating to always having to make it over and over. Saving Base designs would be a great feature!
