I have to manually turn on Game Booster (after opening it) for WoT, but for one other game I have it opens itself and turns itself on automatically.
And maybe you guys knew this, but with supplies on sale... you can go to the "Store" then "Consumables" and buy tons of repair kits and medical kits for half price. In the long term this will save you silver. So far I have 312 repair kits and 163 small first aid kits, plus some fire extinguishers and such. Buy 'em today, last day for half price I think.
I never knew we could buy tons of them at one time when they are on sale.
