By far the best, most polished eBook experience I've ever had the pleasure of using. Didn't think I'd ever step away from Lithium but here I am with my cloud storage synced, custom themed with my own imported font Readest setup. Just how I envisioned it. Apple Books, my original favourite but not attainable on Android, has been beat. PERFECTION. One update request though: Add the search through the text magnifying glass icon on the book tap view quick settings. Right now it's two clicks.

There's no option to keep the bottom navigation menu (recent apps, home, back) on android, it always hides that part! I want it to be visible all the time! Add that option please. When trying to auto-save and auto-fill account details (user and password), I saw that the bitwarden shows this app name as "tauri.localhost"! And it doesn't work with bitwarden's autofill. Fix it please.

it is a very good app and very thoughtful made but one thing that bugged me is that when reading a web novel , the chapter name is only shown in the header and not in the page itself. so while reading I didn't notice that a new chapter has started(also in paragraph mode). pls change this and it will be the best reader. love your app
