I was bored so i wrote this application. It's nothing special. it just displays some configurable notes (see screenshot). When you click on the note the buttons and the entry appear. just enter any text to into the entry and press 'Apply' or so...
How to install:
Extract the archive, and open a terminal
cd to the unzipped folder
sudo make install
This depends on your distro.
then just run the 'notes' command
have fun with it
