The issue: the GM doesn’t have an easy way to access any but the primary health bar.
In order to access other health bars, the GM has to either enter Player View mode (at which point all health bars can be edited by the icon in the lower left corner) or open the character sheet. This makes using multiple health bars for NPCs
I would like to see a means of quickly affecting all of the health bars, like the Heal/Damage HP interface. It seems like it wouldn’t be too hard to have the Heal/Damage HP interface actually drop down a list showing all of the health bars, instead of just the one…
