You have revolutionized the world of ebooks with this excellent software. There is still a lot of work, such as using artificial intelligence to improve voice reading of books. This allowed not only a more natural voice and diction but also reading PDF files. But the immediate suggestion I have is another, you inserted, well, a button for us to add files to the book. This is very interesting because, for example, I have books with audios and other PDF worksheets. Grouping everything together makes perfect sense. However, the viewing of this material is hidden. To know that that file has other material, I will have to edit the metadata and click on the files button. This is not practical at all. What do you think about creating a kind of floating indicator on the cover photograph so that we know that that book has more material. It would be interesting if this indicator was clickable. Maybe it would give a list of the files. Another suggestion to enrich this button is to create sub files and sub folders to better relate the material, instead of just being in a list. Lastly, I love your browser for accessing caliber on other devices with the caliber server connected. You did an excellent job!! What I miss is more options. For example, knowing what each user has read or downloaded, allowing them to only download a specific number of books per day or month, or even controlling the time spent in that library. This helps a lot in controlling children. Count on my donation you deserve it!!!!
