Hi there,
It would be a good idea to allow to remove attributes after they have been used in a transformer.
For example, I could keep an attribute to be used in a tester transformer, and once it is used in the tester transformer I don’t need it anymore so I set up an ‘AttributeRemover’ afterwards to remove the attribute. Doing this often clutters up the workspace, so it would be good to have a checkbox inside a transformer to remove the attribute after it has been used within a transformer so no need to have an attribute remover afterwards.
This can apply to any transformer that uses an attribute, like AttributeCreator, StringConcatenator etc.
