One good feature in this community is when we use @ icon, it will list down the name of users so we could call them. However, in most cases we are only calling people in a question (and not the entire community) , so it would be nice like when we press @ then it list name of people in the current question first and then draw a line and contain list of users in the entire community. This would improve usability of this forum and the logic is to filter users in the question and add them at the top.
