Do them as separate custom plugins, like so:
//=============================================================================// Plugin Name//=============================================================================//============================================================================= /*: * @plugindesc Description * @author Author *///=============================================================================(function() {//-----------------------------------------------------------------------------// Window_ActorCommand//// The window for selecting an actor's action on the battle screen.Window_ActorCommand.prototype.maxCols = function() { return 2;};})();Just for the sake of organization and in the event that you break anything while playing with the functions.
