Even if it does become a feature of the base game, I would still like to see an API for setting arbitrary markers for each group member.
For example:
Code:
SetGroupMemberFloatingMarkerTexture(unitTag, primaryTexturePath[, secondaryTexturePath])
SetGroupMemberFloatingMarkerPulses(unitTag, primaryPulses[, secondaryPulses])
SetGroupMemberFloatingMarkerSize(unitTag, size)
SetGroupMemberFloatingMarkerColor(unitTag, r, g, b, a)
ResetGroupMemberFloatingMarker(unitTag)
The values would then overwrite whatever the globals are which got set with SetFloatingMarkerInfo and SetFloatingMarkerGlobalAlpha until ResetGroupMemberFloatingMarker is called.
