These Quality of Life improvements will be coming in the next release:
Traps and Defenses:
Traps and defenses (X-Bows, Inferno Towers and the Eagle Artillery) will be automatically reloaded for free when you log back in to Clash of Clans. Note: The above defenses still require ammunition, so if you don’t log back in they won’t be reloaded automatically, and will eventually run out of ammunition.
After the next update, you’ll find the Magic Item inventory button in the Town Hall/Builder Hall instead of the Clan Castle. This is to reduce the clutter of buttons you’re greeted with when clicking on the Clan Castle, and also to allow players to see their inventory while in the Builder Base (where there isn’t a Clan Castle).
Someone accidentally donate a Goblin or Wall Breaker? Leaders and Co-Leaders will be able to delete donated troops from other Clan Members’ War Clan Castles.
Even better suggestion in the Builder menu. We’ve made it quite a bit smarter, and also you can scroll and see everything you could build.
