Bullet Columns is a free Chrome add-on developed by Y2NR. It falls under the category of Browsers and is specifically classified under Add-ons & Tools.

Bullet Columns allows users to create sortable bullet lists with columns. The add-on provides three columns, with the right two columns designed for digits but can also be used for texts. Users can easily reorder the lists by dragging the bullet symbol on the left, and delete values in a row by clicking the "x" on the right. It's important to note that the input data is not saved automatically, so users need to manually click the "Save" button.

The latest version, 0.6, includes minor bug fixes. Bullet Columns is a useful tool for those who need to organize information in a sortable and columnar format within their Chrome browser.
