- Add a UDF and try to save the design. This doesn't work.
- Save to a directory and try to execute another query. Shouldn't be able to do this at all.
- Explain should be disabled when executing a query. This goes for query history as well.
- UDFs label should be "User Defined Functions" or "UDFs" rather than "UDFS". Maybe "UDFs" with tooltip "User Defined Functions".
