Elle est unique. J'apprécie énormément la grande variété de langues prises en charge, j'apprécie de pouvoir voir la traduction d'un mot pendant ma lecture en appuyant simplement dessus dans la langue de mon choix. J'adore cette appli, merci beaucoup!! Je trouve aussi super cool que des livres électroniques soient disponibles et proposés dans la langue choisie directement depuis l'appli, c'est super pratique et génial. Merci encore pour cette appli. Je comprends pas pourquoi cette application n'est pas beaucoup plus populaire. II y a juste une chose que j'aimerais voir changer, quand je clique sur un mot pour le traduire, l'application me ramène à chaque fois quelques pages en arrière... J'aimerais beaucoup qu'elle reprenne là où je m'étais arrêté, merci! **Developer response:** Merci beaucoup pour votre merveilleux commentaire et pour avoir pris le temps de partager votre expérience avec Booklex ! Des retours comme le vôtre me font énormément plaisir et me motivent à continuer à améliorer l’application et à développer de nouvelles fonctionnalités. Merci également d’avoir signalé le problème concernant le retour en arrière lors de la traduction d’un mot. Je vais examiner ce comportement de plus près et travailler sur une correction afin que l’application reprenne toujours exactement à l’endroit où vous vous êtes arrêté dans votre lecture. Encore merci pour votre soutien et vos encouragements. Des commentaires comme le vôtre donnent vraiment envie de continuer à faire évoluer le projet ! ### 5/5 — Корисний додаток *2025-11-10, version 2.1.7* Дуже класний додаток!
