It would be good to have some feedback on the offers one makes to the seller. Atm, one only knows if the offer is accepted and a deal goes through. But it would be good to have a "decline" button so we know that counter party saw the offer and is not willing to go through with it. Or at least have a "seen" or "read" status so one knows when to move on and make an offer to another seller. Kind of like with a status messages on whatsapp or telegram... Or even have a little chat space, perhaps the parties are close to a deal, maybe a bit higher offer would cinch the deal?
