there are many books where a lot of information is hidden in footnotes

German uses special characters as quotation marks (i.e. »…« or „…“). When we split long paragraphs to smaller sentences (Automatic Translation: ON, Original Formatting: OFF) each sentence ends at a full stop. German dialogs, where each quotation is ended by « or “ and not by a full stop the end of each line is not correctly recognized, and the whole exchange is seen as a single long sentence (see attachment). It should be possible to choose different "sentence terminators" according to the language. In case of German, a sentence should terminate by full stop, « or “

It would be better if there were more copying capability of the text in the book: allow selecting and copying more than one paragraph at a time, without strict restrictions. Otherwise, you have to copy 4 times and perform the AI action on the same word/phrase 4 times accordingly.

Let's consider adding an option to import user dictionary and use for word translation. This dictionary could be in StarDict or Mdict format (that already contains html for the card definition). Rationale: Online dictionaries and GPT models are somewhat good for "mainstream" (mostly European) languages. But they are not always correct for a word definition and even the phrase translation sometime works so-so for other languages (Asian including CJK, Turkic etc.). For example, the basic "听错" Google translates (for some reason) as "не ослышался" (not misheard), while it is exactly the opposite (misheard). Sideloaded user dictionaries could be obtained from other open resources (wiktionary mono- and bilingual dictionaries, cedict, handedict, or even dict.cc - see https://github.com/koreader/koreader/wiki/Dictionary-support ) by user or made available on the SmartBook site. Using a trusted dictionary will allow user to either cross-check machine translation, or even configure to always use it for word translation. Alternative Of course, we can use word translation with Android built-in popup "share-like" functionality, but it is inconvenient, and most of all, this could just as well be done with other popular apps like Kindle or even Google Books. These apps already provide word lookup with built-in dictionaries and even sentence translation with an online translation service (for free).

Sometimes I also want to improve the original text, e.g. I download subtitles from YouTube that are not broken into sentences, there are only words but no punctuation marks. I would correct this while reading.

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!

Is it a way to redesign as to translate an entire paragraph not with a button, but with a gesture. For example, swiping across the text to the right - translating this paragraph, swiping to the left - pronouncing the paragraph.

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.

Advantages: We immediately receive a finished deck, ready to transfer to other devices, send to someone or put in the repository. There is no need to first send the data to Anki, then export it to .apkg and then have a transportable file. Many users use SmartBook on a tablet, and Anki on a smartphone because using SmartBook on a phone is not convenient, the screen is too small, but for learning and memorizing a phone is more convenient, since it’s always at hand (and the vertical screen format is more suitable). This means that not everyone has Anki on their tablet and SmartBook on their phone. This process does not present any inconveniences (SmartBook -> .apkg -> Anki) since Anki users are more advanced and export to Anki does not happen often (as soon as new words accumulated in the dictionary). Anki has an effective mechanism for processing duplicates and cards moving from deck to deck, so users can handle it by themselves. In .apkg you can put anything you want, icons, any other media, etc.
