Barracks up/down arrows useless, replace with 'clear all' button
Title says it all. moving a unit order up or down in the barracks takes a long, long time, and you lose positional focus, requiring you to search for where the unit order you were moving is after it finally registers.
Its far far faster to simply erase everything (but the current build) and place a new troop order using sliders on the left.
Its obvious from the time delay the up/down arrows use a tremendous amount of server resources, so this change would be better for both BB and the players.
