All you wanted to suggest

I just have concerns as to whether or not the pricing model could be kept indefinitely without a raise of price in the future. In short how does the app limit and overusage of the AI tokens since everyone use case is different? Wouldn't it be a better approach to allow users to attach their own API token so even in the future case of an inevitable price increase on all generative AI services, users of this app wouldn't be affected by such and be double charged in the economy? I personally wouldn't mind paying a one time option to unlock the ability to attach own API key. Please take this into serious consideration!

I think it could be a better user experience (especially for ereader) if you touch the empty space close the modal. I think it is faster than dragging down and more comfortable

Add automatic backup/restore of the reading location to external cloud storage google cloud or dropbox, as it is implemented in moonreader. I suggest making this function available for a one-time payment. When you close a book or minimize the application, the application will automatically write the reading location to a file in the cloud storage, and when you open the application, it will ask the cloud storage if there is a different record of the reading location and offer to go to this place, if it is different, and if not, the book will simply open. In general, the mechanism is identical to moonreader pro.

Sync books between devices of a single account

I'd like to save some phrases or paragraphs to re-read in the future, further investigate about it, etc. This is a basic feature that almost every other book reading app has and I think I'd benefit greatly its overall user experience

I would like to have a shelf of the books, that had been read. Sometimes need to mark the book - had been read. It would be wonderful if i could create my shelves... or folders... i'd like to have min 3 shelves - Reading now + Have read + Will read soon

Function: -pause -back -forward -repeat original text significantly improves narrator, making use more comfortable, useful and enjoyable

When I add a new fonts for both my native language and the language I want to learn ... change background and text colors ... i wish I can save these as a unique theme... adding a name to it and if it's for day or night ... then make it active ... this way i can add different themes and use any of them easily without having to change the colors, fonts, separately each time i want to try something new and I can't go back to how it was before easily also it would be very very nice to share themes with my friends via a link and if you made a page in your website for people to share there's, gathering spot where we can all swap cool designs, get inspired, and make our reading experiences even more enjoyable! Thanks!

After reading a book, you will rate it, and based on the books you liked, ChatGPT will advise you the next one

Backup - no option to save locally (to the main storage of the gadget)

When I translate a sentence using ChatGPT, it can be seen that it does not have access to earlier or later sentences. Modification of the prompt in such a way that it has access to the context of the sentence in which it appears could improve the translations by light years.

In the home section, percentages of the book's completion are often stuck or wrong. For example, in the previous book I read, it showed 100% completed even though I was still midway the book, now on the current one I'm reading it has been stuck at 52% even though I'm on the last couple pages already.

Add support of the mobi books format

The proposed improvement for app is to add the functionality to manually mark individual chapters as read, even if the user hasn't fully read them. This feature allows readers to maintain a sense of progress in situations where they may have already covered certain sections or are revisiting a book. Importantly, this should not affect the reading speed metrics or progress calculations tracked by the app. The app would continue calculating the user's reading speed based solely on the chapters they have fully read, ensuring that the overall metrics remain accurate and unaffected by manual chapter markings.

Hello a nice option for brightness is to add + - button because at night it is hard to swap to find the specific brightness you want
