it would be nice to auto-hide the Omen frame during pet battles since
a) it doesn't provide any information
b) may block the action bar based on where you have it positioned

I second this. i was coming here actually to request this very same thing

My solution to this for now

Add following to top of "UpdateVisible" function

	if event == "PET_BATTLE_OPENING_START" then
		self:_toggle(false)
		return
	end

add following to "OnEnable" event registration

	self:RegisterEvent("PET_BATTLE_OPENING_START", "UpdateVisible")
	self:RegisterEvent("PET_BATTLE_CLOSE", "UpdateVisible")
