Great app! But please add the following features: (1) Renaming the EPUB files. The names that the authors give them can make them useless when sorted alphabetically. For example, instead of "X Ch. 100", the name is "X Ch. One Hundred". (2) Reordering the Notes and Bookmarks by time added or location. (3) Making Note content searchable. It'll be of great help to search for Note "Battle at X" instead of having to memorise enough of an exact phrase to search.

Without doubt, this is still the best app for reading epub books. I've used it for many yrs and have always been happy with it. Hw a few extra features would be welcomed, such being able to increase and decrease font size more than is currently permitted; also it wud be handy if font size moved in 5% increments, rather than just 10% increments, as it currently does. Likewise with the margin sizes. Such tweaks, at least for me, wud make the app that little bit bettr. Thx.

Working really well. I bought it mainly for the extra colors and I was not disappointed. There are 5 added colors, making it 10 colors in total. The original 5 colors plus 2 blues, dark red, orange and pink. A dark green would have been better that one of the 2 extra blues but all in all, it's amazing. Thank you!
