sometimes I need to just change the casing of letters in a field name (e.g. a field has GUID and I want to make it Guid). smart rename does not allow me to change the name if the new name is exactly the same saying that a column with this name already exists.

so I change the name to GuidXXXX and then on the generated script remove the XXXX and the script runs just fine.

I think smart rename should not warn that the name exists if I am just changing casing of the name
