Post-its. For me, nothing beats these as a simple reminder tool. I wanted something similar for reminders on my computer, and didn’t really want to stick some yellow sheets to my screen. So I went for the virtual version of post-its. These are simple floating windows that get overlayed on your desktop, and can contain some text.
There are many, many applications that can do virtual post-its for you. However, they all seemed to lack one feature or another. That was until I found Hott Notes.
