"I recently started using the XFCE Desktop Environment instead of GNOME. I 
missed GNOME's Places menu, however. This panel applet brings much of the 
functionality of GNOME's Places menu to XFCE.

"The plugin looks a lot like a launcher with multiple items in a menu. The main 
"launcher" button opens up Thunar at the user's home directory. The arrow 
button opens up a menu with two sections: system-defined locations and 
user-defined locations.

"The system-defined locations are consistent with Thunar (including their 
icons). The plugin parses the ~/.gtk-bookmarks file for user-defined bookmarks, 
keeping a cache in memory. When the arrow button is clicked, if the file has 
been recently modified, this cache is regenerated.

"The plugin currently has no preferences. User-defined bookmarks can be 
modified with a file manager or by manually editing ~/.gtk-bookmarks."
