Would it be possible for you to change the white background to a transparent one?
Sure. Actually, I just re-enabled a commented-out line that did exactly this.
(I disabled that because I thought the colors might be badly readable, but I never bothered to test it. And then I only used mine as a large image instead of the text version and no one else used it so I didn't care. But I agree, now that some use it, the white background looks rather ugly. And I think the text color is readable pretty well.)
Edit: Also, I've added a new feature. You can have all your characters listed at once now (result see my sig), e.g.:
[img]http://psstatus.uglyhorst.de/Ash, Peter; Pikachu| freedommaster,MaStErFiGhTeR.png[/img]
will result in:
(Just to demonstrate improved error tolerance too.)
(Obviously, "advanced usage" will only work if just a single character is specified)
