Make troop selection 'disappear' once troops are deployed
This may not be of problem for iPad or other tablet users since they have huge screens so ignore that. This suggestion is more towards us iphone/galaxy players with much smaller screens.
When using a complicated army composition in war such as Holowiwi (hogs, witches, loons, wizards), plus additional troops: archers, barbarians, wb not to mention two heroes 4 spells and clan castle troops, that is already about 13-15 slots. Keep in mind that this army is precisely planned specifically for a base and doesn't apply to everyone;I could gowipe or gowiwi all day without this issue.
Given, sometimes I have to look down and I'm uncertain which troops are gone and which ones available. My suggestion is once all of a certain troop is deployed, have that troop selection slot disappear so that it will prevent chaos and confusion.
