The mines are producing all the time , each mine have capacity for resources it could save , once you want , you click "collect resources" so the resources goes to your base and then you can use them . each mine will have it's own button , but what if you had 4 of each mine types (would be around 20 mines) will you be pressing them all one by one ? it would be annoying , so somewhere in the base there should be a "collect all resources" button , how about clicking on the system will popup a small info box about the system,its location and a button of collect all resources ?

Yes you will be able to expand to other planets , but those planets could be destroyed and taken over by other players , so you have to leave some ships/fleets to protect them , and any ally/friend who leaves his ships near that planet is automatically taking some resources . i wanted to have a button for those planets as well (collect resources) but what do you think is better , one button to colelct resources from those planets (as in the main base) ? or when clicking on it , a cargo ship with the resources is sent to your base (when it could be attacked as well ) ? but it would be a problem for those far-far-very-far planets (it might take a month depending )
