Great, but missing an obvious feature

I love this app. It has done a great job keeping me organized and within budget for Christmas. However. I wish that it had a log in so that more than one person could see what you have purchased and add to the list of things. My mother and I use this app for my kids and it is time consuming having to send her a shared spread sheet, her update her list, then she sends me a spreadsheet to update my list. If we could both log in on the app to the same list and only one person has to enter something and it updates on the other persons site, that would be awesome and I would immediately give 5 stars.
