Currently a wire is highlighted with red color if error occurred on it. It would be nice and saved a lot of time if one could see what error occurred on a wire.
Existing workflow requires to do a few extra steps to see an error on a wire (if recording wasn't enabled beforehand).
  1. Error occurred, wire is highlighted
  2. Start recording on a wire or connect log widget to it
  3. Reproduce steps that led to an error.
