Advance troop build option
An option to link your barracks together. I want to build 40 archers, 40 barbs, 40 goblins, 4 wizards, 8 giants, 8 wb. If you had an option to link the for regular barracks together, What you build in one barracks, is built in the other three barracks. So I would build in barracks one 10 archers, 10 barbs, 10 goblins, 1 wizard, 2 giants, and 2 wb. This would then be built in the other three remaining barracks. Saving the annoyance of scrolling to the other 3 barracks and repeating the whole process over. It would also make sure all build times are the same in the 4 barracks. And they would finish on time. You could do this with the dark barracks as well
