Stylus

Not "ish", but "us", as in "us" the actual users. Stylus is a fork of Stylish that is loosely 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 majority of code has been rewritten to optimize performance.

Stylus was created by users, for users, in response to Stylish being taken over by a new development team. Stylish-for-Chrome now has extensive analytics enabled by default, and the UI has been over-simplified for casual users, thus becoming far less user-friendly for power-users who actually create and edit styles.

The main objectives in creating Stylus were to remove any and all analytics, and return to a more user-friendly UI. Other important new features have also been added, most notably a backup feature, and an intuitive and customizable automatic update function for styles.
