Coming almost a year after the Calibre 4.0 series, Calibre 5.0 is here with some major changes. This include the ability to highlight text in the E-book viewer, which is one of the most requested feature for this powerful ebook manager. Users will be able to use colors when highlighting text in ebooks, as well as to use all sorts of text formatting and styles, including strikethrough and underline. In addition, you can even add notes to your highlights. All the highlights will be stored in the respective EPUB file, which makes them easy to share. In addition, you can browse all your highlights in the Calibre library using the Browse annotations tool.
