Upgrading KOReader

Hello all :)

I have two questions:

(1) How do you upgrade KOReader on the Aura One? Is it merely deleting the KOReader directory in Adds and then downloading the latest nightly build and extracting it to the Adds folder?

(2) When Kobo's Nickel is updated, it causes problems with KOReader menu. What would be the best way to update the Nickel firmware and keeping KoReader menu working?

Thanks :thanks:
