Las ventajas más obvias son estas
Enable object editor hack: This allows you to enter custom rawcodes for objects created in the object editor.
Enable no limits: If checked removes World Editor limits (doodad/neutral building/etc)
Syntax checker options: It is better to keep these options checked for optimal jasshelper compatibility, else world editor's
syntax may cause you issues or even crashes when enabled.
Mute editor sounds: Turns off the startup sound, the undo/redo sound, and the sound that it makes when placing/deleting.
Disable first save warning: When a map is saved for the first time or a Grimex tool is used on unsaved maps, a popup will tell you to save your map again. This popup will be disabled with this option.
Customize Test Map Settings: Sets the options to load startup settings to the map.
Quita algunas cosas que se hacen molestas como los carteles del nombre de tu mapa, el sonido al abrir, los límites de objetos colocados en mapa y te permite escribir el rawcode que quieras al crear algo en editor de objetos.
