While troop trees have a vertical scrollbar to scroll up and down, there is no horizontal scrollbar to scroll left and right.
I tried modifying EncyclopediaUnitPage.xml to add a horizontal scrollbar but to no success. It seems that the game does not "see" that the troop tree is too wide and make the horizontal scrollbar visible.
Is it possible for the devs to add a horizontal scrollbar? Or if not, at least can a dev guide me as to how to add one?
Any help would be appreciated.
