+// @description    [@@BUILDNAME@@-@@BUILDDATE@@] Decrease the portal detail level used when zoomed out. This can speed up map loading, decrease the amount of data used, and result in faster display. Only applies when zoomed out to show no closer than L3 portals. May stop display of the smaller links/fields.
