I need to be able to create a playlist of books in a specific order. Also the organization ability is kinda janky. I would like the ability to add a bunch of files to a specific folder but they just go to the main library and there’s no quick way to move dozens of files to a new folder I created. Also, if you delete files from the actual Bookjack folder manually, they stay in the app and you have to manually delete from the app one-by-one. A multi-select/select-all feature would go a long way. **Developer response:** Adding to the next update and fixing everything else! Thank you for your feedback. ### 2/5 — Potential *2026-05-09* The app seemed like it would work great and has potential for an easy to use app, but I was not able to rename or delete folders which makes it a no-to for me unfortunately. ## Frequently asked questions about BookJack Player ### What audiobook formats does BookJack Player support?
