The Jira Board Width Updater (Beta) is a Chrome extension developed by James de Klerk. This free tool falls under the category of Browsers, specifically Add-ons & Tools.

The purpose of this extension is to address the problem of Jira board item summaries being cut off on larger screens, despite the availability of extra space. It aims to solve this issue by updating the width of the Jira board, ensuring that the item summaries are fully visible.

It is important to note that this extension is currently in beta, which means it is still being tested and improved. Users may experience occasional issues where a page refresh is required for the extension to work properly, even after the initial installation.

Please keep in mind that if Jira fixes the issue of cut-off item summaries on larger screens, this extension may become irrelevant and can be uninstalled.
