TLDR's lists

Essentially whatever you want. Some ideas could be:

• A to-do list of parts you need to buy for a specific job
• Finding how to group your orders amongst retailers when you're buying multiple parts
• Sharing information on a website/forum of what parts are needed for specific jobs

The big benefit of creating a list is that the prices are always getting updated, so the information is always relevant!

It means that the list can be seen publically by other users. You can link to the list from other websites and forums to show people the contents of your list. You can unshare the list at any time and the list will become hidden.
