-#     AllowTrackBothResources
-#        Description: Allows players to track herbs and minerals at the same time (if they have the skills)
-#        Default:     0 - (Do not allow)
-#                     1 - (Allow)

-#        Note:        The following are client limitations and cannot be coded for:
-#                     * The minimap tracking icon will display whichever skill is activated second.
-#                     * The minimap tracking list will only show a check mark next to the last skill activated (sometimes this
-#                       bugs out and doesn't switch the check mark. It has no effect on the actual tracking though).
-#                     * The minimap dots are yellow for both resources.
