I can well understand the "Whew!". No worries.
Despite the various software issues I've reported, the word list filter is already really useful for computer assisted proof reading.
During the past few days, I have generated word lists for the KJV OT, KJV NT and also for the KJVA DC books. Likewise for the WEB OT and WEB NT.
It's helped me to discover some minor typos in the latter which I've been able to report to the editor in chief.
It's only after someone starts making in depth use of such a filter, that these things begin to emerge as issues and/or suggestions for enhancing TextPipe.
