I fail to see� what does not work.
Renaming Spec-Core to ValueHolders works.
Even if ValueHolders isn't already there, it is created.

The only thing I encountered, the ValueHolder entry
wont' show� up in the rename dialog, if
- the Package doesn't exist (of course, thats ok)
- the Package is empty ( but it still works).

Or should we prevent to rename a category
*XYZ if package XYZ doesn't exists?
