content: Dont know what liquid mode is as all my docs PDF books are over 200 pages. Wish there were more customization options to the reader settings and a page flipper like the one in Google play books. Highlights not accessible in dark mode or current material for some reason would like an easy notepad to hide or show toggle for notes on the whole document instead of having to split screen with another note app. Think student. Would like to see integration with Googlewikidictionary quick popup
