Jira Tool is a free Chrome add-on developed by Alan He that aims to enhance the functionality of the popular project management tool, JIRA. This add-on focuses on expanding the quick filter feature in JIRA, making it more efficient and user-friendly.

With Jira Tool, users can now take advantage of several new functions that improve the filtering capabilities of JIRA. One of the key additions is the support for single filter, allowing users to easily apply filters to their JIRA boards and quickly narrow down their search results.

This feature provides a more intuitive and streamlined experience for users who heavily rely on filters for their JIRA workflow.

Additionally, Jira Tool offers the ability to copy title and link. This feature allows users to quickly and conveniently copy the title and link of a JIRA issue, making it easier to share or reference specific issues within their team or across different platforms.

Overall, Jira Tool is a valuable add-on for JIRA users who want to enhance their filtering experience. With its support for single filter, arrow hotkeys, and the ability to copy title and link, this add-on provides additional functionality that improves productivity and efficiency within the JIRA platform.
