The ability to search through the descriptions of all of my videos and find a specific line and delete all text after that would be game-changing for my ability to manage all of my videos. My descriptions follow a very similar format but are not always the same throughout so I can't use the find and replace text to update bulk, repeat sections of my descriptions. However, if I could find and delete all text after a certain line, I could then find that same line and append a new description ending to all of the videos.
