This sounds like an excellent premium account feature, something folks would actually pay for. So, to amend the original idea...
Proposal:
A premium feature, under either Administrator or Merchant, which would allow demanding resources from all villages, for all of your cities, at once. This would add a link to the right of Miscellaneous on the menu you get with Administrator.
Reason:
The time it takes to administer resource gathering over your villages, especially once you have multiple cities, is intense. This would provide a way to minimize the number of clicks it would take. The trade off would be that it would only be for demanding resources, and you would have to choose the same option for all cities.
Additionally, the current method of demanding resources does not work with certain devices, such as Droid, for example. A different menu structure from demanding resources that supported such technology would be a positive addition.
Details:
A link to the right of Miscellaneous called "Demand" would open up with the correct premium feature. Clicking this link would open up a window similar to the current demand window for a village. This window would have either three or six options, depending on if you have booty researched. Only the three or six time options would be displayed, not the resources. Clicking on a time option would globally make that time demand on all of your villages, irregardless of what city they belong to. Number of resources would depend on the individual villages. Villages for which demand is not yet available would be unaffected. Resources would be credited to their city as currently.
Balance:
Premium feature. You would only be able to select one time option, globally. You could only do demand, not loot or demand troops.
Summary:
Save premium players the time clicking on all of their villages to demand resources. Help those players with carpal tunnel syndrome.
