If you’ve checked your notifications recently, you probably noticed the slightly revamped notification panel. I quite like it, as it gives more quick filtering options than before (although it’ll take a little while to get used with them being to the right of the panel rather than the top), however I feel like having yet another filter, an @ mentions one, could be pretty nice, especially since that is a filter once you go to the notification tab on your profile.
Here’s a very lazy edit of what it could look like since I’m too lazy to do an actually good edit:
Note: this is a copy/paste of the same topic on another forum (evidenced by the screenshot), as someone alerted me that it could have not been implemented on Discourse itself rather than hidden by that forum’s staff. As it turns out, they were correct.
