Notifications for mentions
Give user the option to disable notifications for group mentions separate from team mentions.
As it is right now, you have to accept either being spammed with every mention of every team you're in, or not get notified for posts mentioning you personally.
Related: I want to mute @channel notifications, but still get personal mention notifications.
By not having this, I am probably have to turn off mention notifications entirely.
Slack has had this option on a per channel basis for a long time. On any channel you can set notifications for mentions, and check if you want to include the @channel and @here or not.
