I would like an "Upgrade Facilities" button to work on one planet. That way I would not have to upgrade everything when I just want one almost complete shipyard to complete as a lv2-3. It seems a shame that I can refit my whole empire, but not just one planet. Note I am talking about stuff in the build queue, not stuff already built.
I would also like a way to upgrade all items in an empire, but not change the build queues. I hate upgrading everything to lv3, then going back and changing all the queues back to lv2 so they can build one a turn.
Does anyone else start a factory at lv1, then put the queue on hold for that Last turn or two while you get the lv3 tech?
