Excellent plugin. One quick technical request for the next version though.
In your Redux options panel, you left your page slug as the default:
'page_slug' => '_options',
As a result, any other plugin or theme using that same slug will cause problems. Both option sets will appear on the page and one will bounce the other from the WP Admin bar.
'page_slug' => 'wabl_options',
Also, do you really need the menu to be a primary object in the WP install? You might want to consider displaying your plugin's options as a submenu item:
'menu_type' => 'submenu',
While the plugin is awesome, it's actually a very minor component of any WP site and absolutely doesn't need top level billing for its settings.
