Structuretree and History page have button to switch between each other
Further we can now enter history page ingame for looking into civilization bonuses and informations f.e. (especialy when random civ is chosen, this is indeed helpful looking up.)
Also in gamesetup it is now possible to go from civ history to civ structuretree to lookup certain units/structure etc. info.
It also remembers what was lastly opened (history or structure tree and what civ) to reopen same page on click again (only in gamesetup) for fast lookup.
