This reminds me: it blows my mind how far behind the publishing industry is in terms of technology. I'm currently editing a tech book, and I get the assets from them as a Word doc and images for the figures in a zip file. I have then "track changes" in Word, save the file, and send it back. For the images, if there is an error, I have to take a new screenshot, write in the doc that there was an error, and then send back a zip file with the new image(s).
This would be SO much easier with github. I could just make my edits and issue a pull request, which would work with the image too. I could even use the commit messages to explain what the error was if need be. Github even has tools to make this process easier for non-tech people (which honestly there shouldn't be since it is a tech book!).
This will be made easier by this tool, but sadly not for me.
