I've been exploring what the different functionalities are in Sigil and what's optimal for me (a novelist).

I'm assuming it's good to have the 'Mend XHtML Source code on:' on the Open and Save settings. (see attachment)

And the second arrow. I should have the CSS Level 2.1 filled in?

Lastly, I don't even have EPUB 3 so I guess that third setting is moot and if I ever do have it it should be on CSS Level 3.

And a generic question:

What is the difference between:

Tools>Reformat HTML>Mend and Prettify All HTML Files

and

Tools>Reformat HTML>Mend all HTML Files ?

As I recall one was the old Tidy and the other the Prettify. The Tidy being super powerful and systemic and best to be avoided, but I'm not sure.

Thanks.
