Hello,
<p>
Up to now we only have pages ans spaces to structure information. I would like to suggest&nbsp; to have another level of structuration, as we can have for instance in MindMaps (MindManager) or in http://www.w3schools.com/ or even in formalisms like SADT(IDEF0).
</p>
<p>
The idea is to have a tree of plans, each plan can have pages structured into spaces, but each plan is itself structured into a tree. 
</p>
<p>
In mind manager, each node can be refined in a sub-tree and we can navigate easily from one level to another one.
</p>
<p>
In http://www.w3schools.com/, the information is well presented on the left side of the site as spaces containing pages. Somes pages are themselves subplan, and when we clik on the, we enter in the sub tree with the same kind of presentation...&nbsp; It is really clear, and efficiant... I&#39;ve made 5 years ago a generator in Mindmanager to generate from the mind map automaticcaly an intranet following the ruels edicted for w3schools. It was actually very convenient .
</p>
<p>

regards
