I'd like to add-on to the ability to work with to-do type lists. Before switching to EverNote, I used an app called SpringPad (iOS and MacOS) until SpringPad was dropped. It had a feature with checkbox lists where you could show or hide checked items in a list. And select all to check/uncheck each item. This worked well for grocery lists or other lists that typically have the same items. I create my list, check them off as I accomplish them and they are hidden leaving only the remaining items. When I was done, I could select all the checked items, and change them to unchecked so the list was ready for the next use.
