When creating the Output of an operator in the properties view, offer a mapping tool to drag functions, input fields, etc to fill in code or expressions.
For example:
in a map's Output Settings view, I can select the Streams > Input > input1 field name and move it with a dragged hover over, but I can not place it anywhere in the Output Settings.
Same would be nice for Functions > Chooser > functions
I can confirm this would be a nice feature... Most of my mappers are primeraly for mapping values from 1 schema to another.
Thanks, Mike. We will look into this.
