A really handy feature is the possibility to change a source provider to allow for the evaluation of alternatives. If the portal does not know how to deal with a parameter, it tells you and allows you to decide what to do with it.
It would be great if there were buttons/links allowing you to copy the entire parameter contents to the clipboard so that you can easily paste them into their destination field in the new connector.
As an example: if I want to evaluate the SAP ADF connector, I can use an existing SAP Table connection to base this on. One of the parameters I then need to work on is the table filter list. This can be a very long field which is annoying to copy paste. Additionally in this specific case, the original field separates tables with spaces, whereas the ADF connector expects each table to be on a new line.
