Just trying to figure this out still. If I were able to put group member health gauges with %s into my player window, seperated by a bar or line or something, or text such as "Kath's Posse" in the screenshot - that would leave the group window with the invite and disband buttons right? And those can be removed right? However, because of a child in the group window, you can't completely get rid of it, right? And as for putting the target, pet hp, and casting time underneath the group member hp gauges, you can't completely remove their respective windows can you? Aside from maybe spell casting window. Is that how it works?
And also, what exactly denotes a child, is any "sub-element" I guess they're called, a child? For instance:
<element>text or something</element>
<whatisthis>who knows</whatisthis>
<andthisone>not me</anthisone>
<element>please help</element>
Would "<whatisthis>" and "<andthisone>" both be considered a "child" of the element "<element>"?
