Windows Vista comes with a cute and tiny Notes gadget with a sticky note kind of look. But it was too small for me and I wondered why they never had settings to decide its size.
I tried downloading some similar gadgets, but none was satisfying. They either lacked features or were too clumsy. After reading a white paper on gadgets, I found it was very easy to make a gadget of our own. But it was easier to modify an existing one with the features we wanted. :)
