It would be great if the warlock invocations from XG showed up together with the ones from the PHB in the classes section of the characters page.

Thanks

Came here to say this and I'm glad someone already did.

Subclasses get integrated immediately, would be nice to see the same for invocations.

I agree that this would be great. I'm surprised it hasn't been addressed yet. Hopefully they see this sometime soon and can fix it.

It has been addressed in other posts. Warlock and Barbarian are expecting a fix to include missing material.
