Selecting all colonies in the Construction Queues Window

you can up grade every thing at the click of a button but as far as I know there is no way to do a select all exept kliking on each of them in the list with the multiple production ques option added and then adding whaterver it is you want to build to all of them

Upgrade all though is kind of harsh on the resources, so make sure you are well prepared to upgrade.

Agreed if I need to upgrade and am not sure I am ready (cant realy afford it) I will use this window to do a system at a time

Upgrade also doesn't work the last time I checked. It adds items to the que but they never get finished.

use it routinely not seen any problems with it apart form the obvious economic costs. I will note that upgrades are added to the end of the planets construction que
