GPS location management
Introduce Alt-A Select All, Shift-Select, and Ctrl-Select for muti-selecting GPS locations in the GPS Tab menu. This idea is only for the ability to multi-select the locations and set HUD visibility options. When doing this all other fields and options would be greyed out. I'm requesting this because whenever I prospect for ores, I tend to generate a large list of coordinates, and this would speed things up in terms of managing the UI.
