Toggle mode of GW even when sleeping/regenerating - because this is the time you plan for your next attack.
You should be able to rearrange troops and spells in Quick train - so that eg. Wizards and giants and bowlers were trained first and healers and wallbreakers last - why? because then you will have troops for donations faster and the optional troop (eg WB) would be last because you don't use them all in every attack
