Amazon Improvements

This inventions concepts includes improvements to Amazon’s website and web software, such as multi-level lists, for an example in the Lists section of the website, having a main list that is named Appliances, then being able to nest another sub-list named Home Appliances, and then being able to nest another sub-list underneath this called Vacuum Cleaners, would be useful and helpful. Also, having a clear indicator of items that have already been purchased when they are listed in the Lists or Save For Later list would also be helpful, to ensure that duplicate items are not purchased by accident. Having the ability to have a gifts list, that someone can share with someone else in their family, or post lists publicly, or even just posting everything in their list publicly, and also being able to comment on items as to why they are wanted by someone, and being able to post the lists publicly, to allow anyone to purchase the things for someone, would also be helpful and beneficial. Being able to isolate items within lists, with data structure search algorithms, such as if the item has been purchased before, and then being able to delete the items from the lists, would also be helpful, or even to move them to another list, or a sub-category under any list called Already Purchased, or Already Purchased , would also be helpful.
