edit: A more general thing I think the Bip does well, that I don't think is mentioned in previous replies here, is that it does away with incremental scrolling with drags in favor of 'scrolling' the whole screen with swipes. I.e more like moving between pages. I think this is more efficient in daily use. I like the new main banglejs menu system, but it's not as quick to navigate as the bip menus.

Regarding what I mentioned in this thread before:
I have now made an app that changes menus so they do this.
