Hi,
Sometimes it's useful to have absolute address, for example to adjust
the window according to the background image, it's quite tricky to do
this with dynamic positioning. If you want everything to be controlled
by the layout manger, just don't use the property and wrap panels
around widgets.
>From your previous description, I think your meaning of margin is some
kind of space left around the border of panel, I think that could be
useful as well, but perhaps with a different name, I'm considering the
following properties:
inner_left, inner_right, inner_top, inner_bottom: space reserved
inside the border
outer_left, outer_right, outer_top, outer_bottom: space reserved
outside the border
Perhaps the naming of margin_* property is a little misleading,
perhaps I can rename them distance_* to remind it they're used as
fixed distance to borders of parent.

In the currently implementation, valign is for the parent widget
panel{
direction = left_to_right
valign = center
panel{ id ="bb"}
panel{ id ="bb"}
panel{ id ="bb"}
}
}
Align all child vertically, but I guess this can be implemented per child.
