Some users prefer certain hosts or providers to deliver their movies/tv shows, for example because they may be consistently fast and/or stable based on the user's location. This script make it easy to visually locate a preferred host by highlighting the row if it appears on a page listing. By default it will highlight 'vidzi', as an example of how it can highlight a host, which of course can be edited. You can set your custom host name choice by pressing the 'Primewire Host Highlighter' menu button, then type in the host name (case-insensitive, partial match works). It will then save the name and highlight its row in yellow on any page list it appears on.
Also, there's an extra feature, which is shown in the screenshot, labeled as 'Autoplay Button'. At the upper-left, there will be a gray button with the active host name in it. Pressing this button will automatically open the first provider link on the page that matches your chosen host name in a new tab or window.
