Ah, okay.
Thanks for the quick and easy reply.
Is this what can be triggered by the load_props param in the {menu} tag?
I don't need the whole content 22 times.
Anyway... i need to know wich is the one that ist used by the template var {$content_obj}.
I'm creating a dynamic template that loops through the content props array and decide where to display what content block.
In brief:
I have several content blocks. For each content block i have additional content blocks with param oneline=true where the editor can enter "left", "right", "top" or "bottom".
In the template i have four areas that are styled to be shown on left, right, top or bottom side of the page.
In this areas i have a foreach loop that loopps trough the $content_obj->mProperties->mPropertyValues array and checks if the value of the content prop that holds the "position" is the one that belongs to the current div.
That works fine but the problem is that the contents in the array $content_obj->mProperties->mPropertyValues are not ordered in that way they are shown in the backend.
So the "main content" (content_en) may be shown as last content block or anywhere in the e.g. the left column.
But i want it always to be shown as first block. No matter in wich area it is shown.
I try to create a plugin that orders the contents that way i want it.
I just name the additional blocks content_en_layout, content2, content2_layout, content3, content3_layout, ... etc. so i can reorder them by the php function ksort($smarty->_tpl_vars['content_obj']->mPropertyValues) since the blocknames are used as the index.
But reordering the array $smarty->_tpl_vars['content_obj']->mPropertyValues doesn't change anything.
Even unset($smarty->_tpl_vars['content_obj']->mPropertyValues) does have any effect.
So this is why i believe the template var {$content_obj} must be one of the 21 other content arrays . . .
But wich one?
And is this always the same?
I know i could assign the reordered array to smarty and use in the template in the foreach loop the new assigned smarty variable.
But this will put another complete content array into memory, what isn't really necessary since it is already (22 times!) there.
I hope someone understands what i'm talking about, since english is not my native language.
EDIT: SOLVED
*lol* Figured it out
$smarty->_tpl_vars['content_obj']->mPropertyValues doesn't exist 
i forgot the mProperties Object:
$smarty->_tpl_vars['content_obj']->mProperties->mPropertyValues
