Recently been fiddling some more with Calibre, and fine tuning it to what I want. Spent several hours reading questions and answers on online forums like Reddit and Mobile Read but haven't been able to solve these problems - whether the solution is out-dated or too vague.

1. For author sorting, I've been able to get author prefixes and surname prefixes to work and be 'green' within the metadata editor. However I seem to have a problem with suffixes, no matter what I do they always show up as 'red'. One forum post suggested using commas before the suffix, but that showed up as 'red' too. Is there any way to get suffixes working?
2. For page layouts, I know how to change the page layout of e-books to display two pages of text side by side like that of a physical book. But I'd like to do the same thing for e-comics, which are essentially images compiled into one. Apparently it's possible to do with CBR and CBZ files, but all of mine are in EPUB. Does Calibre support a two-page layout for comics? And if so, how do I change it to that?
