When colonizing or otherwise entering a new planet screen, I typically lay out most of the basic infrustructure all at once. You know, a few factories, a starport, a farm and what have you.
In doing so, it would greatly aid folks like myself who can't think as fast as we click if the list of improvements wouldn't reset to the top of the scroll bar when double clicking an improvement to be built. Thus, we could just keep clicking in the same spot to get the same building on different tiles quickly. As it is now, you must scroll down each time to get something towards the bottom of the list.
This would also be handy if emplimented in the build queue list. When moving items up or down in the build order, it would be handy if the scroll would focus on the item being moved, rather than the top of the list.
As with all devices, they are only as good as their interface allows them to be. I love this game, but it would be even more enjoyable if it could think for me so cant just click my way to victory!
