Papertrail Mark is a free Chrome add-on developed by Mikuláš Dítě. As an unofficial extension, it is not affiliated with Papertrail, but it provides a useful feature for users of the popular logging tool. With Papertrail Mark, users can easily add large marker separators to their logs with just a button click.

This add-on is particularly helpful for organizing logs and making it easier to navigate through large amounts of data. By adding markers, users can quickly identify important events or separate different sections of their logs. The simplicity of the button click makes it convenient and efficient to use, saving users time and effort.
