Advisory information: Some of FunnelWeb's diagnostics provide a detailed explanatory paragraph. While this information might be useful the first time, it has the capacity to clog up a listing file if the user has made the same error many times. To solve this problem, FunnelWeb could be modified so that such explanations are only displayed the first time the error occurs.
Abort after n errors: A facility could be added to prevent FunnelWeb's scanning, parsing, and analysing phases from continuing if a certain number of errors have already been issued.
