>I like the idea of being able to get rid of it by an option on it. It could be another way how to teach user about GTG features.

Yes, absolutely, that's why i like it. Seems like conversation:
App: “Hey, dude! something changed here! wanna know about it?”
User: “I guess...”
App: “In this mode you see <something-depends-on-current-mode>”
User: “Gotcha!”
App: “By the way, if you want to go back just click here.”

Brilliant!
However, we should remember other approaches of implementation this idea.
Key word is Microsoft — they show us great [2] examples of assistants which should help users to understand an application and interact with it.
And the consequence of these examples is it shouldn't be annoying (see my previous comment [1]).

[2] Great for learning how it shouldn't be, because many users actually hates those assistants.
