create a joomla module

Create a simple study aid module which will allows the user of a website to highlight any piece of text. When highlighted a button will follow the user down the screen on the right hand side, once clicked, These will be copied to the bottom of the screen with each highlighted text retaining its place within the website to bring the user back there if they so wish. From there, the user will then have a number of options. They will be able to rewrite, amend, rearrange, add their own, delete, click on a printer friendly version etc., all the while retaining the link to their original page position. They will also have the option of converting the notes into an interactive memory map.
