"difficult for you to grasp"? so so grumpy...tsk tsk tsk.
Sorry about that. I really didn't try to come off all condescending, it just kinda happened. But I want to reiterate that Civilization is all about strategy, and to bring big plans into motion, you have to be willing to take the small steps required to realize them. If everything is just done for you, there's less satisfaction to be had when all is said and done.
But I will confess, even on Noble difficulty, all the management that needs to be done, starting from the Renaissance era onward, tends to give me a headache, even with the new and improved BtS interface. So it's not that your ideas don't have merit, it's just that they're going too far and removing major elements of gameplay. I think most of your suggestions would be successful if they were implemented on a smaller scale.
The building hopper could work, but only if limited to 5 units/buildings. I can't imagine that having any more than that would still allow you to build in reaction to your surroundings and opponents.
Changing production in multiple cities simultaneously is an excellent idea, but not for selecting all cities in your empire or on one continent, since that has limited usefulness. The City Advisor Screen should have two features for changing production in cities without entering Full or Reduced City View. "Set Multiple City Production" is a feature which lets you change the current assignment of all cities which you previously ctrl-clicked in the menu, and even includes a switch to set the new mass order to take effect immediately (top of the queue) or after all previously queued projects are complete (bottom of the queue). The second feature is "Assign to Big Plan," which I will talk about next.
As for setting all cities to try and build an army of units as efficiently as possible, perhaps this "Big Plan Customization" menu could work. First, you would create an order for units and buildings (as simple as 11 Libraries, or as complex as 8 tanks, 2 transports, a battleship, and 2 mech infantries). Once you've drawn up your Big Plan, you go to the City Advisor Screen and select a city's current production. A drop-down menu of all units and buildings in your Big Plan are shown, and you simply select which to build, and do this for all cities which are most suited to the task. As you assign units and buildings from the Big Plan, they are removed, so once you've chosen two cities to make Transports through the Big Plan feature, you cannot make any more Battleships through the Big Plan feature (but you could go into the city and set it up there if you wish.) Finally, if any cities request something new to produce, and there are still things to be built from your Big Plan, they will be offered at the top of the list. So this Big Plan feature requires management still, but it's made a lot easier as the game helps keep you from building more of something than you previously specified and reminds you to stay on track.
Wow, that was a bit of a mouthful.
