I do not know if this has been suggested already or not I think this will help with the fun of the larger maps.  Personally I like to play the very large maps.  I like the epic feel.  The thing I do not like is the repetition in setting up a build queue.  What I would like to see are governors you can assign on a per planet basis.  Let me explain what I mean.

You can have the option to at anytime place the control of a plate under a governor.  There would be several types of governs to choose from that are include in the game.  For example a governor that will focus the planet of making money, ships, research, etc.  These governors would then chose the build order, planet focus and what ship to build if the planet has a starport.  These basic governors are for the general crowd who does not want to have to micro-manage every one of their plants on the larger maps. 

While the stuff before is good it is not what I really want to see.  What I want to see is the ability to make custom governors. I typically play on large maps and focus my plants on, production, economy, research, or influence.  The build pattern is not very different from one planet to another.  I would like to create a custom governor for each type of world that I can set after I get the world and have it automatically create the build queue and baby-sit the planet watching for specific triggers to happen. 

This is how I see it working.  There are two main parts of the governor, the build queue and the trigger events.  When making the governor you can add a specific building or a type of building to be built.  For example wanting to initially build a lower rank factor on a new world verse building the max rank factor on an established world.  The building added to the general queue would also have options for each building.  For example if you are building a morale building, put it on the highest tile bonus square or only build a lab on my econ world if there is a + 700% tile to put it on.  Another example is farms; personally I do not put more then two on an econ world because more then that will cause significant morale problems later when they get upgraded.  If a world has a food bonus tile of 100% I want to put a farm on it but if it has a bonus of 300% or 700% I do not want to put it on it.  Also when the second farm comes up in the queue I want it to be able to look and see if there is already a farm on a 100% bonus tile or not and not build if there is.  The governor would also keep track of what has already been build, so when you get a new world from another civ you can put a governor there and they will use what of the existing structures they can and replace the rest with whatever you what the planet focused on, they will also be able to clear the existing build queue when they do this.  That’s the general ideas with the build queue, now triggered event.

The trigger event list is essentially a list of actions to take if a specific event happens.  There are already some triggered events in the game.  These are the auto improve events on buildings and unusable tiles.  One additional auto events would be to refill the queue of planets with governors when new squares become available.  Beyond that if I research a new factory shortly after, for example, a new econ building I want the factor to be improved first.  The event table would notice the new factory and put all factory improvement projects before the other econ improvement projects.  The ship build order would also be handled in the event list.  Another example is reactors; they are not initially available and would not work in a build queue, so instead you have it in an event.  When a reactor becomes available have the event turn one of the factories, not on a bonus tile, on your production worlds into a reactor.  The last event of significance I can think of is planet focus.  Initial I want my planet focused on social production, when the buildings are done I want it to switch to either military or research depending on the planet.  Later when it starts upgrading buildings I want it to switch back to social.  There is a lot of possibility in this and would help a lot in elevation the hassle of micromanaging the hundreds of planets in the larger maps.  I do not think this would take away from game play in that you can create the governors to suite your style.  The only thing it eliminates in the reputation in setting up and babysitting worlds that have a simple build pattern.
