To get nice box centered at middle of screen, but content in box left
aligned use
HBox(
  HStretch,
  VBox(
    VStretch,
    Left(<content>),
    VStretch
  ),
  HStretch
)
This is really just an overly complex way of writing
HVCenter( Left( content ) )
because
HBox(
     HStretch(),
     content,
     HStretch()
   )
is the same as
HCenter( content )
and it's the same in the other dimension, i.e.
   VBox( VStretch(), content, VStretch() )
Hi,
thanks for hint.
I try it now as I have another change in installation proposal where I need same layout and found that HVCenter does not work at all. see [1].
Also I found another cave-eat. Each element has to have own Left as Left(VBox()) does not work as expected. See mentioned PR for final solution that produce layout I want.
