“This nifty application allows you to create ebooks
using the graphical interface without getting your hands dirty with
coding. Despite being a relatively new application, Sigil already
sports all the essential features that simplify the process of
formatting ebooks and generating ready-to-use EPUB files.“Sigil supports most common formatting options such as bold,
italics, and underlined as well as different text aligning options.
All these features can be accessed via the buttons on the main
toolbar.”
