First off, amazing work: supercell is absolutely writing tomorrow's textbooks on how to do game development right!
A minor fun addition would be a new sound when picking up the air sweeper. I call it the foghorn, so such a honk would be hilarious. Too much for use when it triggers its effect. I adore the stone-ish sound touching the spell factory.
An option for coleads to propose a set of people to include in war before committing, above and beyond who has marked themselves in or out, would be very handy. Something right on the current war setup menu would be nice, such that one leader defines a set, and a second only has to committ the decisions.
There are numerous screens I can't donate troops from, making me back out of investigating the opponants constantly.
Probably covered in sim attack sections, but practicing war attacks on clanmember maps would be particularly handy.
