Request: TreeStyleTab Support

[ertyz]

I actively use TreeStyleTab addon for tree-organize my internet pages experience. It would be great if Tab Grenade support it.
Two things what I need:
1 Save tabs tree structure in TG web page (&nbsp should be enogh), like:

X website
    X website
    X website
    ...
X website

2 Restore tabs tree structure after "Open all". If session Manager can do it, maybe TG can do it too?
