Add chapter 17. In \todo I put two figures in which I copied your TikZ code to show writings and arrows, but the arrows are not displayed. I added the \caption package at Olaf's suggestion. Let me know if it's okay. I've also put in the latest changes made by Phyllis. https://www.dropbox.com/s/0js49r47s0qu621/CinelerraGG_Manual.pdf?dl=0
