If you open the world information screen, then open one planet, switch to resources tab, open a second planet below it in the list, open that planets’ resource tab and scroll to the bottom, then scroll up and down a bit (I think enough to cause a refresh event on the first planets’ panel), the first planet switches back to “Details” view, leaving its panel at the expanded size to show resources. Not vital but one for your list.
By world information screen, did you mean Places -> Worlds and then select any worlds from here?
Sorry. Yes, that’s correct. Also forgot to mention this is on Mac OS version, in case it is platform specific.
