The most important thing to know is: This initial prototype version is NOT collaborative, it just stores your outline data in POSTDATA and cookies. In other words, NOBODY ELSE CAN SEE YOUR ITEMS, just you. Obviously this is contrary to the actual idea of the app, and will be fixed in future!! But there's other stuff to fix first. At least it is vaguely functional so far.
Another Warning! The cookie expires when you close your browser (or maybe sooner?) and will have limited capacity I think! So for now it's not even a very reliable storage system for yourself.
Other notes on this version are in a separate notes page, to keep this page tidy. Details of planned features are now in the TODO list page.
