Small adjustment to when the "active vers" is shown in the top navigation

It seems that when you scroll down, the verse that is topmost visible is the verse that is shown to be "active" in the top navigation button.
the number changes when the top part of a verse comes to the top-edge of the viewport.
And continues showing that versenumber until the next-one comes to the top edge.

it might be a good idea to adjust this slightly, because fon instance in picture IMG_0837.PNG you see that only half of the active verse is visible. Could it be good to have the "topmost fully visible verse" to be the active one?

Also, I wanted to bookmark the last verse in a chapter, i cannot because i can't scroll it fully up to become the active one.
