detachable toolbars

[Bernhard Rumpler tttech com]

Hi,

HandleBoxes can be used to make toolbars (and other widgets) 
detachable. This means a HandleBox can be 'torn off' to be
displayed in a separate window and then reattached to it's
original location.

My questions: 

1.) Is it somehow possible to reattach a handle box to 
different locations, not only to the original one?

2.) Is there any good mechanism to reorder toolbar portions
like it can be done in many MS-Windows-Applications, where 
there are handles on various toolbars? Is this the functionality
implemented in the new toolbar for gtk-2.4? (Are there only 
sliding toolbar buttons or can whole toolbars be moved and 
reordered?)

any help appreciated!
Bernhard
