The Tails distribution is often used as a live, portable desktop distribution which can be used to browse the Internet anonymously and communicate more securely. The distribution is testing a feature which would allow users to install a package and have it remembered and installed again automatically in the future. "We've designed and implemented a user interface to select additional software packages and make additional software persistent. Users are now able to decide, for each additional piece of software that they might install in Tails once, whether it shall be installed automatically in the future." More information on how the feature works and how to provide feedback on it can be found in the project's news post.
