PostVerta – Roman goddess of the past

sketch of a design for a UI to allow browsing alarms and associated images, or vice versa, via a variety of navigation mechanisms.  Designed for use by pointer only, if necessary.

The red arrows mean “previous/next critical (red) alarm” and the yellow mean “previous/next warning”.  You could extend this model to incorporate add’l graphic signifiers, to ease use on non-keyboard devices.
