War Layout - TH Level Switcher
Many players have th11 or th10 accounts and would like to participate in wars using th9 or even lower levels.
It would be great if, after a player updated this TH, he could somehow have access to his lower level village on a frozen state (unable to update buildings or troops). There could be a button to switch to any TH level that the player has already passed. Maybe creating a new "workspace" with the same 3 layout slots (war). People would use this to participate in championships, for example. They could enter a championship using their TH9 version village while their current village is a beginning TH10.
