Format editing to suit one's preferences is good. Unfortunately, it has a flaw that a heavy reader will soon discover: it doesn't do true author sort. Sure, it puts the list of books in order by author, but if you have a lot of books by a prolific author, you're gonna be scrolling forever. (Apple Books is also awful this way.)Needs to have an author-sort that returns a list of authors, so one can tap-through to get the authors books. (Which should then be internally sortable by date-added, alphabetical, or – and this is a tricky one – publication order, which might have to be added by the user.)Ideally, it would also have a way to change the cover (say, you have Phonto and are making covers for fanfic from AO3), but I'm not seeing this just now. I'll try to come back and edit the review if I'm wrong.There's also no way to give money to the devs? Concerning. We lost Marvin (the ideal ereader) because the app wasn't drawing in enough to sustain the App Store fee.

Developer Response
You can find all books from any given author contextually by tapping and holding (or tapping on …), selecting "Contributors" and then selecting the contributor that you want. You can also search by author, this is supported as well. True author sorting can be difficult because EPUB files often lack a string to sort them properly, so you end up with a mix of cases where either the first name or last name is listed first. Feel free to contact us through our support (https://support.thoriumreader.com) or Discord server to discuss this further, we're always glad to receive this sort of feedback.

I’ve been looking for a replacement for Readest since they’ve started paywalling some essential features.So far, I really like Thorium reader! Like a previous user said, highlighting would be a nice feature to have. But, that appears to be in process.Additionally, I’d like to see scroll mode on iOS and a sync functionality with desktop. Particularly WebDAV.Overall, I really like what I’m seeing! I do think the mobile app is much more refined design-wise than the desktop app. I find the Mac desktop app (intel) a bit clunky and not very visually appealing.

Hello,Highlights and scrolling mode for EPUB (it's already available for PDF) are both on our radar for this year. For sync, we'll support OPDS (including progression support) later this year, which will make Thorium Reader compatible with multiple self-hosting solutions. A standalone sync feature is further in the future with no ETA yet since we'd like to ship an Android app before.We'll continue to stick as closely as possible to iOS/iPadOS/macOS to deliver a fully native experience.Thanks,Thorium Reader Team

I am currently using this reader app because this is the only way that I could check a digital book out from my university library. While I appreciate the ability to read the text, I do have ADHD and dyslexia and accessibility functions are lacking. It can read to me which can help me better understand the material versus reading myself. For best comprehension I need to both hear and read along. I am not able to do that in this app. I am not sure if this is a function of the reader or a limitation of the book itself. This is an area where the developers could really improve the app.

Developer Response
Improving our support for audio is at the top of our roadmap right now. With our 1.4 version (planned for October/November) we'll introduce support for audiobooks as well as additional controls for the read aloud feature. Being able to read and listen at the same time is on our list of planned features, with controls over what gets highlighted (sentence, word or both) and how (control over color and style).
