Yes, I've seen people using the "Rename"-Button (=> delete and recreate) 
to order a folder... Wired, but the result is: _objects are a ordered tuple.

Indeed...

Returning to the starting point of the discussion weeks ago? Interesting...

I like the idea of the OrderSupport-Mixin-class. But maybe we shouldn't 
introduce a new additional meta_type "Folder (Ordered)". Instead we 
should extend the normal Folder with OrderSupport as originally 
proposed. People who don't need order support don't have to use it. All 
other people can use the OrderSupport without converting their 
Folder-(or-derived)-Instances.
