Easier to see Maps
 

The "X" used to show the location of a group member is both too small and a low contrast color.

I cannot find any file I can modify to make these changes. Please point me in the right direction.

If the SOE developers are the only ones who can make these changes, please do. Better, make it so we can.

Thanks
===================================
EDIT: Thank you both for the information. I was able to change the color to a bright red. I have also been editing my maps, one at a time, to change map lines to black, so the red shows up well enough.

I will keep trying to find a way to change the "X" and its size.

i know you can change them, it's in your character INI file. (not the UI one, the character one). i do not remember how to find the area that you need to change though - with luck, it's labeled something like 'group', and it's just basic RGB colors. my group Xs are red. don't think you can change the size though. and unsure if you can change the color of your own arrow (though i would like to)

look for your UI_charName_ServerName.ini for the heading

[MapViewWnd]
GroupColor.red=0
GroupColor.green=0
GroupColor.blue=0

Dunno about the arrow or the size. You may be able to change the size in your EQUI_MapView.xml
