I'd love a feature that creates a pop-up on the POS screen when the server attempts to start a tab for someone who has previously walked out on a tab. So, instead of starting a new tab, a window would pop up and let the server know that the person trying to start a tab has walked out on their tab in the past and will prompt them to complete the transaction instead of opening a tab. This is primarily for the POS, but I was directed here to make the request and it would work for tables as well.
