donate war troops while scouting their bases...
I don't know bout everyone else, but when I'm donating troops to my clan I like to look at their base layout to determine what I want to give them if they haven't specified... it would be an awesome addition to be able to select a clan member's castle while scouting them in war and have the option to donate to them directly from there as it would save time and hassle of going back to war screen and finding them and donating there. This feature would actually be a good addition to regular donations too... If they had an active request or if they have specified units requested for war the request message would be displayed.
