The JIRA Extension is a Chrome add-on developed by vlady.zn that provides additional functionality to the JIRA kanban board. With this extension, users can retrieve HTML reports from their kanban board, customize the number of columns to be exported, and add a description tab during the export process.

One of the key features of this extension is the ability to search columns using keywords, making it easier for users to find specific tasks or issues on the board. Additionally, users have the option to customize the style of the board by removing unnecessary items for a better overview. The extension also allows for the addition of sequential numbers to the board.
