Which isn't a bad thing.
At the moment I'm aiming at the lest amount of functionality.
Next thing I want to do is adding Zope-awareness and put
objects in a Folder/wCustomizer .
How hard is it to move a Simple Item DataSkin to a Customizer?
BTW. After I have done that successfully I intend to make the DataSkins
Plugins instead of Zope Items. That's the my goal at this point.

Ahhh, good.
Magic is a wonderful thing, but it also makes understanding a bit harder ;-)
About the ZClass still of propertysheets, is that when I add a
OFS.PropertySheets.PropertySheets attribute to my object?
Can I use the OFS.PropertySheets.PropertySheets for that and
does it play with ZPatterns?
I use PropertySheets for allot of multi language support, storing
properties in separate languages PropertySheets.
