I don't think I saw this elsewhere as a suggestion, but could have missed it.
As we adopt the platform more, it is becoming more typical to be within the environment most of the time (having the window on A project within ACC on another screen - though sometimes a different tab that isn't active). I'm not sure it'd be possible, but having a "popup" option for notifications specifically when @ed in something like the RFI Activity Log could help streamline receiving information - since it doesn't auto-refresh to show it, and I think the only notification is an email (based on the set frequency), a more dynamic information of someone being informed would be helpful.
This could be helpful, if not possible, for when we "subscribe" to a folder as well.
