1. What's new in 1.2? Changelog doesn't mention a thing and I'd rather not update blind.
2. The link to plugin page shown in WP admin panel's Plugins page that leads to http://www.snilesh.com/resources/wordpress/wp-pagenavi-styling-plugin/, returns a 404 error. The site doesn't have any posts about the plugin.
3. Hopefully this fix gets incorporated soon: https://wordpress.org/support/topic/plugin-wp-pagenavi-style-put-in-a-submenu-fix
