A neat small plugin. All is working as expected. I would to have an option for a custom message during timing run. Something like "We are starting in... min", but I've just amended Browser.html to my needs.
A good further improvement will be a bit more of text customization settings, like outlines and gradient. Text (GDI+) properties in OBS may be a good source of inspiration :)
Regardless, thank you for your hard work, this plugin is useful :)
