Currently it is possible to select (multiple) fields when adding fields in the DatabaseJoiner. What I am missing is the possibility to add the field(s) with a specific name.
I am bound to add them with the name they have in the joined table, leading to a AttributeRenamer after almost every DatabaseJoiner.
It would be much more straight forward to have the option to add the new name/alias directly in the DatabaseJoiner.
