This now (5.2.0) has a message box of the form 1 of 10
This suggests to me we could do away with faded arrows
<left/previous/back
right/next/forward
and instead either have the arrows off or on
so
0 Notes no arrows no box
1 Note no arrows box visible
2 Notes on Note 1 > visible box visible
Notes between 2 and 9 both arrows visible and box visible
On Note 10 left arrow visible box visible.
If the layout became < box > it would also help
Finally it would allow the choice of a solid arrow head in a primary colour or black to improve visibility
This might also apply elsewhere when < and > are used
