While it's cool that specific @mentions will highlight the text in yellow, it can sometimes be a hassle to scroll all the way up through a ton of text to find exactly who's in desperate need of your attention.
No sleep for the weary.. or the support team.
Enter the recent mentions tab. by clicking the '@' logo at the top-right hand corner of the client, you can view the past 7 days of mentions that included you, with some customization options.
There are two ways to quick-jump to the mention, for quick reference:
1. Hover over the 'jump' icon and watch it light up, but that'll get you to the same place in the server.
2. If you just want to jump to the text channel and Server, but not straight to the mention, you can click the text channel name above the mention bubble, and you'll see the latest message there.
