For those who have Sony devices which didn't get the new "TaskKiller" or "Close All" -button, I have this for you (of course, no root needed)pulled from Xperia E1 KK firmware (published today)This button has the ability to close all recent apps at one click, first appeared at Xperia Z2. Unfortunately many KK updates didn't include it, but now E1 firmware did and it's compatible with all 4.4.2+ firmwares which didn't have.Finally!!!
