Background setting for widget works great. Black.
But I can't set anything in the large tag cloud. Looks like I get only 5 digits to set it. Huh??
I did a work around by setting transparent.
Something wrong with the background color field in the plug-in settings? Like I said, the widget settings appear to be fine.
Super plug-in. Esp the fact that it floats categories. This makes tag clouds worthwhile.
