I used xsl/css to match where and whether the parts should be generated 
(like you do). Currently you can an example of that in the 
site2xhtml.xsl of the css-style-dev skin.

e.g. If no search box is selected the second logo will be aligned right. 
  Another example is the breadtrail, you can choose an alternativ 
location for it and it will be rendered "on demand". The css-file 
contains predefined alternativ locations.

I *do not* deliver always everything to the client. The changes I 
applied for the css-style skin can be used as well in all the other skins!

Yes, but I do not really like it! I think to add single elements to the 
skinconfig.xml will end up in an overkill of the file. Imaging I want 
all css be overriden, I will end up developing them and copy'n paste 
them to skinconfig! That is not *copyless*!

That need somebody that have experience with the portal, right? If we 
are not familiar with the portal engine I reckon it would not be as

I would like that in the future I can edit my forrest pub (the layout as 
well) within lenya. I would concentrate *my* energie in enabling a web 
based layout editor in lenya rather then in forrest.

I think I will have a look in the portal again in my upcoming vacations. 
Maybe you are right and that would be the best solution.

Right now I really cannot say anything about that!
