Linux Notification Center

A haskell-written notification center for users that like a desktop with style. The notification center receives notifications via DBUS (like any notification daemon) and shows them in the upper right corner of the screen. The notification (if not specified in the notification otherwise) will also be shown in the notification center even after the notification disappeared by itself. The notifications can be clicked to make them disappear. Notifications can be replaced by the use of the replaces-id feature of the notification specification. The notification center can (optionally) show user-specified buttons in the bottom that can be in two states (highlighted/not highlighted) and that can run customizable shell commands.
