Upgradable builder huts that will allow you to protectively store your gold/elixir/dark elixir.
In example:
Next level builder hut would cost double the gems of what your second builder hut cost (500 gems) to upgrade to level 2 and once upgraded you can choose to store 1/2 million gold, 1/2 million elixir or the equivalent of 1/2 million to dark elixir ratio that cannot be looted or only a miniscule percentage of it can by attackers.
Original prices of a builder hut:
1st Builder Hut - free
2nd Builder Hut - 250 gems
3rd Builder Hut - 500 gems
4th Builder Hut - 1000 gems
5th Builder Hut - 2000 gems
Upgraded Builder Hut Cost's:
Level 2 Builder Hut - 500 gems
Level 3 Builder Hut - 1000 gems

I hope those reading take interest to this idea, it's a win-win for both us and supercell. It would be a way to save our farmed goods from being looted.
Of course changes could be made, this was just an idea and the algorithms could be to the liking of supercell.
