Fair enough, no argument there since we can agree the grimoire concept itself is not a problem (many would not). But, if forced to decide between the two, focusing on implementing the overall storytelling fixes and the like as with TTK first and then working on integrating the grimoire with a later expansion (versus the opposite order), I'd keep the grimoire where it is every time, it's only a mild nuisance to use the app but the lack of story crippled the game. (That's most likely a false choice, of course, but it gets the point across.)
