Suggested App Improvement

Level 2
I love this app! I’ve had it for 3 years and love the updates being made on it and can’t wait for more improvements! I would love to have the option of being able to mark items as pending and being able to choose a prospective buyer. I think this will be a great way to secure a pending purchase and remind sellers that they have committed the item to someone. It will also hold buyers accountable for their commitment. I would also love to be able to rate/review a prospective buyer if they were a no-show. Hopefully this way it will limit the amount of misleads given to buyers and limit accidental commitments made by sellers. What are your thoughts on this and what new improvements would you like to see?
Level 5
Perhaps allow me to find user names to follow opposed to simply bumping into them by questions or an item that interest me?
