Thanks for the info regarding Clammings! I tried to figure this out via SEB Lems, which had one of namida's custom skill panels in Old Formats, but resorted to the standard green again in New Formats.
I could offer you, after I'm done with creation and stuff, a tester version of United. It will use custom panels, rank signs, menu signs and logo. So you could see how I've done it as well.
Also Reunion has the LP IV panels again, if you want even more examples.
