UWFlow++ (2021) is a nifty Chrome extension that provides a convenient way to preview the UWFlow rating of a course by simply hovering over the course listing. It offers an effortless solution for users who want to quickly access information about a course's rating and description without navigating away from the undergraduate calendar pages.

With UWFlow++, users can effortlessly gather important details about a course by hovering over the course link. The extension displays the course's description and UWFlow ratings, giving users valuable insights into the course's quality and reputation. Additionally, by clicking on the course name in the popup element, users can easily access the UWFlow page for more comprehensive information.

It's worth noting that UWFlow++ (2021) draws inspiration from the now deprecated UWFlow+ extension by Matt Dsouza. However, this extension provides an updated and functional alternative for users seeking a seamless way to access course ratings and descriptions on the undergraduate calendar pages.
