I have a file with multiple titles that I would like to be able to break up into the separate titles, provide with tables of contents, and if at all possible, correct the typos (okay, I'd correct the typos if I cared enough, which I doubt I ever will.)

Before I download Sigil (and start learning coding - eek!) I'd like to know how much of that Sigil will be able to do/help me do. Can someone give me a brief rundown? Thanks!
