Is there a way to create nested categories in AdminUI or in Workspace folders? Does anyone know if this functionality will become available in a later release of LiveCycle?
Also, why isn't there a rename option in Category Management in AdminUI?
No, you can't do nesting.
The other questions, I can't answer.
You could probably change the category name by directly updating the category table in the database, but that's a bit "naughty".
