Sticky Notes, Ubuntu Desktop

Ubuntu comes in with an integrated Sticky Notes. You just need to right click the top or bottom bar and pick add to panel and add the sticky notes icon will be where you want it. 

After it you need to right click on the icon to make new and you can stick them to the screen. The cool thing about it is that you can go into the prefrences and ask the sticky notes to leave the notes on whichever desktop(Linux can have several desktops) that you created it(my case I have one for coding, one for surfing and one for my robotics stuffs).
