TODO list generator

Hey /prog/. I'm working on a web based todo list generator. My idea is to take a text todo list and separate each item/task into a separate 'box' which can be hidden when the task is complete. The main reason for this is to take todo lists from sources such as emails or websites that can't be edited easily and put them in a format that is more presentable to the user.

I have written a php file for presenting a form for the list to be pasted, then each item/task is output in it's own div which can be hidden when the user wants. Also, the user can add notes to tasks. The main problem with this is that the list cannot be saved and so any changes are lost as soon as the browser is closed.

What's the best way to save the status of the list? I'd rather not use a database since 1. my current hosting plan doesn't provide me with a database 2. I'd like this to be able to run locally

I was going to ask how you could possibly need help writing a to-do list manager of all things, but then I noticed you're using PHP.

You're never going to get it working to your satisfaction.
