By making use of IsInInstance() and the right event listener, the addon should be able to hide and disable itself when an instance (dungeon or PvP) is entered.

Good suggestion! With the dungeon guide on the way, we'll probably have it load that automatically when entering an instance, but for now this is a good idea :)

I had implemented this as part of my trial WoWPro_Instance changes.

Shall I make this change for the stock addon?

Jiyambi?

I would appreciate it, though having it as an option that can be turned off would be ideal.

I will add an option in the configuration section that is by default turned on that disables the current leveling guide when in an instance.

Sounds good to me!
