Specifically on the two cards "Books by Rating" and "Books by Page count", it would be cool to see a tool-tip preview of say the top 3 to 5 books. Since the granularity/focus is books, it would be cool to have a little review on the same page, or maybe even a navigation link to Books filtered by that rating.

Edit: changed title from Dashboard to Stats

Literally. Sometimes I want read scifi or fantasy books that don't start saga or trilogy or whatever.

Would be possible to add a filter here and there (e.g. in the "Trending books" page) like "self-contained", "one shot". You get it.

Custom Sorting Options (Lists, TBR etc): Sort by Author, by Series, by order in series, perhaps multiple if possible (like you can do it Excel/Google Sheets: Sort by ___, then by ___, then by ___. Basically more advanced sorting. :)

I wasn't able to find a way to delete my account.
I even searched the GraphQL API to no avail.

When editing an author and selecting a new image for them, it shows up in the preview fine, but once saved, the image isn't applied and going into the edit screen again yields weird information about the image.

I would like to be able to promote some lists to a first-class position in the dropdown menu for books, rather than have them hiding in a secondary menu. I want to be able to QUICKLY add search results to my Owned, To Be Read, or Want To Buy lists.

Adding a button allowing you to go back to the list of Lists on a profile from inside a List would be nice, or at least showing the tabs to conveniently navigate to the rest of the profile like can be done from the Want to Read, Read, Currently Reading lists

Add the ability to click on stats, for exemple when looking on how much fiction or non-fiction books you read, it would be nice to be able to click on for exemple "non-fiction" and get a list of all the non-fiction books that you read

For those trying to learn a new language, be it English or something else, it would be useful to have the ability to set goals to read X number of books in Y language

When adding books, especially when they link but don't have complete data, can we add the Country and Language based on the ISBN-13?

Suggest similar authors based on genre or themes to a given author to help people find books, additional to being able to similar books and or series.

A page where you have all the books in the database but you can filter it by genre, popularity, release year and rating. Like what letterboxd has. I think it would make it easier to discover more books for people to read

Owning multiple editions of a book (ebook, physical, etc.) currently causes a book to be shown multiple times in the owned library view.

It would be nice to have those merged into a single item and then have a section on the book page to show which editions you own of a given book. Or at least a toggle to hide duplicates in your owned.

It would be very nice to have a view for "recent releases" and "upcoming releases". The app GameTrack (https://gametrack.app) for tracking your video game library and played/want to play has this feature and it's very useful.

Essentially any book you mark as "want to read" would appear in the upcoming and recently released to alert you that it's available. This could be in the "Discover" section or a widget on the new beta dashboard.

Another step further would be adding another widget or type of upcoming/recent for any series you have read books in.

Some genres have some very specific tropes that are often things readers look specifically for (I'm looking at you, Romance genre). It would be wonderful to have a way to include the major tropes in books - enemies-to-lovers, for example, or grumpy/sunshine, etc. That might allow users to find other books that they'd like based on the tropes (rather than a much broader genre or mood only).

Rather than just reviewing single books, being able to do a review on series entity would be a very nice feature

This might be a heavy/impossible lift given the current data model, but doesn't hurt to ask... There are cases of "box sets" or other collected works that are multiple books collected under a single ISBN. Unfortunately, each individual book has the same ISBN and there is no way to distinguish the individual books within the set, even if they're clearly distinct.
E.g.
9780063392939 - lotr box set
9781632364616 - akira box set
9780740748479 - calvin & hobbes

Ideally there'd be some way to have separate editions for the individual books that are still tied to the same isbn, or having some "version" of the single isbn edition that can be linked and tracked with the individual book entries.

Also, having the box sets themselves represented as a single "book" isn't really accurate and might make sense to have these represented as a separate category in itself. There are examples of box sets that have unique ISBN's for the box set itself, but the individual books still have their own unique ISBN - less of an issue, but treating the two as separate but linked would still be nice. E.g. 9780321751041 - art of computer programming box set, but the individual books have different isbn's.

The Books Read summary under the Stats tab shows the wrong edition in my opinion, since it doesn't show the edition I've actually read. Under the Books tab it shows the right editions as Read though.

My guess is that it works like this because a book isn't counted more than once even if you've read it multiple times (I'm not sure if that's the case though), but it's actually really annoying when this stat shows completely different editions than the ones I've read because I can't recognise the books.

The same applies for lists (except the Owned list which is already connected to specific editions) and prompts. Especially when I pin a prompt to my profile it annoys me greatly when it shows an ugly cover.

I would like to be able to choose which edition is shown in these cases, and by default it should be (one of) the edition(s) I've read.

As time marches on, To Be Read lists grow to unreasonable lengths. I'd like a feature that uses various criteria to help me prune this list from time to time.

I envision a few options. Confidence scoring based on past reads, time, and platform popularity feel like easy places to start.

Right now when selecting language and country, you have to scroll to find what you need.

It would be nice QoL to be able to search within the dropdown.

There are libraries like select2 that do this, as an example.

My books read this year in the stats view should be in chronological order, preferably jan-dec order.

Currently you cannot add books from inside the list, only from the book.

The books I'm currently reading don't had a finished date. I'd like to be able to sort that listing by start date (desc) so the books I've started more recently appear at the top.
