####Why?
When I open my team's phabricator install, the first question I'm usually looking to answer is, //"What tasks & revisions am I not fully up-to-speed on?"//
The activity feed and email/notifications help, but there's often too much noise.
####What it could look like
My knee-jerk UI implementation would be to simply place a small icon next to "updated" objects... here I simply added a blue asterisk next to the task #:
{F930540 size=thumb}
//designskills//
Once I view an object and return to the workboard, the 'updated' icon would go away.
####Zen
The knowledge that I'm absolutely caught up to everything my team is working on and discussing... it's "inbox zero" for phabricator.
###Bonus:
In tandem with this feature, the comments/changes history on a Maniphest task could have a visual indicator highlighting the point in time you last viewed the object (i.e. "everything below //here// in the history is new:")
