Maybe a useful feature, help sanitize output column names

This is just in the name of ultra user friendliness. I noticed that you can create an output field with a trailing space

Hmm, or maybe an indicator somehow that you have a mismatch between column names (or types). The connection just brings back a null without a complaint, which has been confusing in the past.

Thanks for this suggestion, I can see how this would be nasty to troubleshoot!
