I also think that colors would help. Sigil uses the following color scheme.

SEVERITY_BRUSHES = {
    'fatal': QBrush(QColor(255, 230, 230)),
    'error': QBrush(QColor(255, 230, 230)),
    'warning': QBrush(QColor(255, 255, 230)),
    'info': QBrush(QColor(224, 255, 255)),
    'usage': QBrush(QColor(224, 255, 255)),
}

I also think that this would be a good idea. (Calibre allows you to add a drop-down preferences menu to the Edit Book toolbar icon.)

I know calibre's Check Book does that, but I think it clutters the GUI, since a validator is not really a tool for editing the book, but something you run at the end of the work.

I think that this is a good idea. Also, if no problems were found, simply display a message box instead of an empty widget.

Other suggestions:

• Allow users to select rows via CTRL+click/SHIFT+click and CTRL+A. CTRL+C should copy the rows as tab-delimited text to the clipboard.
• Add an export button that allows users to export all messages as a JSON file or a tab-delimited CSV file.
• Display a status bar message whenever epubveri is checking the book, checking for updates or downloading them, letting the user know whether updates were found.
