We all obviously use different troops for different needs (looting, trophies, war). And those even differ within themselves. It would be awesome to set up a quick, pre-selected army with just a hit of a button. Tab 1 could build you a looting army like giants, archers and bombers and disperse them throughout your barracks for even training times. Pekkas, wizards, hog rides for war ect… Just speeds up the time you spend selecting each unit individually. You customize your army’s the way you want in each tab.
