First question is why do you want a forge ? Knowing the feature you need out of it is what should drive your decision.
Personally I would question the benefit of allocating ~5% of your work time to anything that isn’t core building your product but that’s up to you.
3 minutes test.

Cons:
Edit: ah ok got it. It does work but not with the same sensitivity, you can scroll down but you need to flick up, most likely because you got screwed by the list of chapters which is most likely also scrollable (my list isn’t long enough to require scroll so I can’t test that). Anyway, I stand by my previous note: “opposite actions” and flick up is not the opposite of scroll down.
Promising beginning though.
