Custom Mentions List

When you type in '@' in a server, you will see a list of members to mention, and as you type a username further, the search results narrow until you find the user you want to ping. What I suggest is perhaps a way to group up, sort or 'prioritize' this mentions list that shows up. In larger servers, where several users may have very similar usernames, this feature could be implemented to make finding the user you want to ping easier to find and can make the mention list more useful in these scenarios. For example, you could change some settings to have the member list that shows by typing '@' to sort by most mentioned, or recently mentioned. You could take it a step further and allow users to make their own mention lists to group their friends to show up at the top of this list. This is merely just a suggestion and not really some big issue that could use attention. Thought it would be a cool implementation.
