Customize Javascript for Sticky Note Script

I have very simple project. I have a website that uses a sticky notes app. Here is the example: [login to view URL] Basically, there is one change I would like to the script. When adding a sticky note, it adds it to the ENTIRE website, but I want it to only add the sticky note to that particular page, not the entire website. This way, each page can have its own set of relevant sticky notes. On the link above, I added a sample with 2 pages so that you may test it. The code will need to be modified so that the Sticky Notes only appear on the page they were created on. On another note, if you are able to complete this customization, I have another task if interested. The website I am using is a Wordpress site. When a user signs in, I would like it if they can view their notes even if they are on a different computer. I know this would require more work, but if you think you can implement this as well, I will pay extra after original project is completed. We can discuss details after completion. I would need a Javascript expert who can provide customization to make the sticky notes appear ONLY on the page they were created on. Thank you
