Slack's little red dot is useful for telling you when you have unread messages, or people directly mention you with @yourname. But unfortunately it also shows up when people use @here or @channel - which quickly leads to you ignoring messages and missing ones that actually matter.
Is there some way to keep having the red dot for personal messages, but to lose it for inane @here and @channel mentions?
