Thanks for the full screen tip with MGutenberg !

When MGutenberg loads, it clearly shows "Looking for books" for a moment before showing nothing underneath. There must be a way to make books show up there. In the help files it says to put the books with the following directory structure:

Documents/Books/Author/Author - Name [Language]

for it to pick them up, but I've tried that and no luck so far!

I'll keep trying. Thanks!
