I didn't want to make the title obnoxiously long. But, this is quite simple.

You have a Free Company, yet you don't seem to pay attention to the <<Name>> part in the floating names.
My idea is simple, for all Friends, Free Company Members, and linkpearl Members, with Free Company taking priority over both Friends and linkpearl

(Say if your friend is in the same linkpearl and Free company as you, only the Free Company part would be in effect)

Your floating name would change colors, depending on which of the three previously mentioned groups the one person is in with you.

Free Company Default would be a Dark Purple.
Friends would be a Dark Orange
Linkpearls would be a Dark Green

Pretty much, in as simple of words, this can be used to find your friends in large clusters of people while doing many other things (Fate grinding and such)

(Sorry if this seems unexplained, got a headache x.x)
