Lights are on, but nobody's home
When visiting the village of someone in your clan, you can see the lights on in barracks and the laboratory. But what you can't see it what troops ar being trained, or what upgrade is being researched.
I get that the visited villages are static and don't suggest we include progress bars, or more dialog boxes to see everything queued up. However, would it be too much to place the tiny logo of whatever is currently being processed as a badge on the building?
In managing clans it's good to know what people are researching in order to understand what new capabilities the clan is adding. There is an element of advise and an element of synergy - hey, you're upgrading golems so I'll upgrade pekkas and then we can donate both at a higher level, etc.
For the troops, how often do we queue up high level expensive troops in war only to come back half an hour later and find that the request has been filled? By seeing what is cooking among the power donators in the clan you can more easily plan what to train without as much redundancy.
Yes, you can ask. But why? There is so much information available via visiting and profile, but closing this small gap would go a long way toward better collaborative strategy.
