is_positionable

https://github.com/meskyanichi/is_positionable

Handles positioning (ordering) your ActiveRecord Objects. Makes use of the "Acts As List" plugin for the optimized background handling of the positioning. "Is Positionable" is a front-end that dynamically generates buttons for moving ActiveRecord Objects "up", "down", to the "top" and to the "bottom". Setting it up takes just 1 word: "is_positionable".
