Currently, when replying to a forum post, we use the "@" symbol to mention a person, but users need to manually search for the name they want to mention. I propose an enhancement where, as soon as the "@" symbol is typed in a forum reply, a list of users who have already replied to that specific thread automatically appears. This will allow users to easily select the name they want to mention without having to search for it. This feature would improve the user experience by saving time and making the process more intuitive.
