I'm glad to see the option to navigate by verse/book/chapter/search hit/article. An improvement over L3 in that we can see at a glance what the current navigation level is set to.
Are there keyboard shortcuts to navigate exactly one unit? Clicking on the on-screen arrow works fine. But with a simple keyboard arrow-up or -down (and also with various combinations of Ctrl, Shft, & Alt + arrow up or down), the screen moves just a line at a time, even if the current verse is several lines long and even if the navigator is set to "chapter".
