Feature Request: Make the Summon Tamable Pet button switch to heal pet if your pet is currently active and switch to pet revive if your pet is actively dead. Or Optional 2nd: Make heal pet switch to revive dead if active pet is dead. Food for thought.
we don't have tech to switch what a glyph on your bar does, so this would require some major rework. but also, part of the gameplay is having to strategically choose what's on your bars.
