User Rating with Activity Bars is a free Chrome extension developed by amtuserrating. It falls under the category of Browsers and is specifically classified as an Add-ons & Tools subcategory.

This extension provides users with a user activity bar that displays the percentage of weekends they have been involved in Amtgard over the past six months. The data for these bars is sourced from the ORK, so users must have a known ORK entry for the activity bar to appear.

The activity bars are color-coded to indicate different activity levels. Users with very low or no activity will have red bars, while users with low activity levels will have orange bars. Semi-active users will have yellow bars, and active users will have green bars. The size of the bar increases as the user's percentage of activity increases.

In addition to the activity bars, the extension also includes ratings for users in various categories. Martial skill is represented by a grey rating, artistic ability and vision by a green rating, intelligence and wisdom by a purple rating, and friendliness and approachability by a blue rating.

A hovercard feature is available, providing additional information about the user when the ratings chart is hovered over. It allows users to provide updated data for other users, which will be reviewed by the curators.

User Rating with Activity Bars is a useful extension for Amtgard enthusiasts, allowing them to track their activity and view ratings in different categories. The inclusion of the hovercard feature adds an extra layer of user engagement and interaction.
