Masna provides a simple graphical interface (GUI) to manage Nautilus scripts. For scripts that are part of the system-wide Nautilus script collection (by default /usr/share/nautilus-scripts; you can change this in the settings dialog of Masna), it manages symlinks in the user’s Nautilus script folder. For scripts in the user’s Nautilus script folder, it manages the file permissions.
GTK+ Recent Files Scrubber is a compact, lightweight Python script which uses GTK's RecentManager to watch for updates to all globally-available "Recently Used" lists (the ones which appear in Open dialogs and the like) and filter out anything in the folders you blacklist. Blacklist entries are hashed to make reading the blacklist not worth the effort.
ZiK is an audio player based on gstreamer. It uses the path of your audio files instead of a music library. Audio files are shown on the left panel as they would be in a browser. The right panel is dedicated to the playlist. Both panels can be shown or hidden. ZiK uses your GTK theme. All formats supported by gstreamer, CDs, and webradios can played.
