Recently I reinstalled Logos to an SSD and discovered that I lost all my personal books. They still showed in my personal book tool, but they were not in my library, so they were unsearchable.
Seems that they weren't uploaded after they were built.
Now that I am recompiling my books, I see that the upload feature isn't even available until after the book is built. If a person didn't know that he had to upload them, he wouldn't think of going back into that resource after it said it was finished. And since it shows up in the library, who is going to think that, oh, this won't reinstall if you get your SSD or move to another device.
My suggestion: offer the option to build book and upload or just build book. don't expect a person to go back into a resource that closes the window and says finished to think that, oh, there is something else I need to do.
