Openbox is a highly configurable, next-generation Window Manager, written by Dana Jansens and Mikael Magnusson. This PND will install it, and add it as an option in the Switch GUI dialog box. Openbox offers fast execution and low resource-usage, and has been configured so you can easily launch PNDs, get online, and use Pandora-friendly keyboard shortcuts.
