Just wanted to share a new applet I have written in python.
It's a sticky notes applet (similar to Notes, but maybe a few more options, and visually different)
Sticky Notes runs in your system tray and can be downloaded from Sourceforge.
There you will find a .deb, .rpm and .tar.gz. If using the source file, the applet runs directly from the extracted folder, or you can install it globally by running setup.py as root.
Dependencies: python (>=2.5), python-gtk2 and python-wnck
The applet is GTK based, so it works on Gnome and Xfce with either Metacity, Xfwm4 or Compiz as your window manager.
It should work with other environments, but hasn't been tested on them (feedback on the sourceforge page is appreciated).
