A system and related techniques to collect and manage a set of incoming message notification objects, such as instant message notifications, email notifications, download notifications, transaction notifications and others and present those objects to the user with an icon, tile or other representation on a dynamically scaled timeline. According to embodiments, the dynamically scaled timeline may present the most recently received object farthest to the right on a notifications bar or facility and slide objects to the left to represent passage of time as those objects age. Instead of presenting those objects on a linear scale, according to the invention, the time intervals in which objects may be presented may be scaled to cause the oldest message objects to be presented on a relatively compressed dimension. The most recently received messages may be presented on wider intervals, to permit the user to perceive differences in arrival of items more clearly.
