To make the menu horizontal, change the following command in the BattleStatus window:
columns: -insert max number of actors here-
So for example, if you wanted a row of 5 actors laid out horizontally, you would change it to this:
columns: 5
To move the position of the block of battle statuses, change the x and y settings of the BattleStatus window:
BattleStatus:
type: Window
x:
type: fixed
value: -horizontal-
y:
type: fixed
value: -vertical-
