The user indeed does not have access to customize the Prettify option, but if you would like to prepare your own version of Sigil and you have a lot of time then you can fight and modify this option or even create a new one to suit your needs.

However, if someone would like to play around, the relevant functions can be found in this file.

Sample XHTML file before:

Only for those interested in my changes (it can be optimized, but I leave it that way for code readability):
Spoiler:
Code:
    // Handle the general case
    std::string results;
    std::string starttag = "<" + tagname +  atts + ">";
    std::string closetag = "</" + tagname + ">";

    if (is_structural) {
        if (tagname == "td" || tagname == "th") {
            results = starttag;
        } else {
            results = indent_space + starttag;
        }
        if (!contents.empty()) {
            if (tagname == "td" || tagname == "th") {
                ltrim(contents);
                results.append(contents);
            } else if (tagname == "tr") {
                replace_all(contents, "\n\n", "");
                results.append(contents);
            } else {
                results.append("\n" + contents + "\n" + indent_space);
            }
        }
        if (tagname == "td" || tagname == "th") {
            results.append(closetag);
        } else {
            results.append(closetag + "\n");
        }
        // if (!in_head && (tagname != "html")) results.append("\n");
    } else if (is_inline) {
        results = starttag;
        results.append(contents);
        results.append(closetag);
    } else /** all others */ {
        results = indent_space + starttag;
        if (!keep_whitespace) {
            ltrim(contents);
        }
        results.append(contents);
        results.append(closetag + "\n");
        // if (!in_head && (tagname != "html")) results.append("\n");
    }
    return results;
