Stylus is a fork of Stylish that is based on the source code of version 1.5.2, which was the most up-to-date version before the original developer stopped working on the project. The objective in creating Stylus was to remove any and all analytics, and return to a more user-friendly UI. We recognize that the ability to transfer your database from Stylish is important, so this is the one and only feature we’ve implemented from the new version.
