Thanks to an earlier post I can now change the location bar colour, but is it possible to change its opacity too?
Solution from KV in case anyone else wants it
Add this to the User Interface Initialisation script (under the Advanced scripts tab on the game object):
JS.setCss ("#status", "opacity: 0.7")
Not sure what should go where ‘gameBorder’ is below though.
EDIT: gameBorder changes everything. It includes the panes, location, and command prompt. status only adjusts the location bar.
