Currently, as shown on BPMCon 17, the display of actual numbers of process instaneces for a task etc. are being displayed using tooltips that are revealed when hovering the respective element in the diagram.
The numbers are of essential importance for the user and should be displaed in a more accessible way. Also, when shown on hover, only one tooltip can be present at a time, these numbers will most like gain their siginificance by comparing them, so there should be a way to show them permanently.
Why don't we use the same kind of badges as in cockpit for this exact purpose?
