In a 20 minute interview, there might be ten times where "Delete Filler Words" deletes a word or two before or after the filler word, too. Currently, my work around is to make a copy the original audio file in the project before I remove filler words, so I can go listen to the original and copy the deleted words if necessary. Just adding the option to make a backup copy of the original audio would be helpful (because it's easy to forget to make the copy and really regret it later). But in addition to that, being able to undo or roll back individual filler word deletions would be an even easier fix. Thanks!
