salaam.
When you click on the footnotes of some ayah, it tells you to go to a previous ayah's footnote to see it. Sometimes this can become annoying if you are in ayah by ayah reading mode and have to go past many ayah's to just see the footnote.
So my suggestion is to show the same footnote of the previous ayah instead of telling to go back to that ayah.
For example in ayah 78 footnote says to go back to ayah 60 footnote, when you press ayah 78 footnote it can display "60[1]:
the foot note
".
So in that way you can even know the initial footnote came from ayah 60 and don't have to go back either.
