On the basis that these things should be idiot proof, as as much as possible, I feel qualified to mention the first two problems that I had:
1) When talking about the Table Of Contents, it suggests pressing "the grey button", but doesn't say where it is. Recently I found it (at the top of the file), and of course that's obvious, once you know. Newbies (like me) don't know. 2) When telling me to select the "Section" environment, I was not warned not to choose the one called "Section*". I didn't look for duplicates in the list (I really didn't expect that), and so it would not number for me. Worse, after fiddling around a bit, I got one to work, but all the others would not. That asterisk in tiny font isn't all that visible, if you are not looking for it. - Mike
