Feature Request: Fading out highlighted ayah when go back from popped up translation.

[benybee]

Hi, I'm new to GitHub. I really wanted to contribute to Quran android if I can. For now I just opening this issue.

I really like the popped up translation when I reading the Quran. Using this without opening full page translation. But, the problem is when I'm going back from pop up translation to read the Arabic, I often forget where the last position of Arabic did I read? Because, the highlighted ayah disappear faster than the popped up translation disappear.

I think the solution of this is to make the highlighted ayah animating to the faded out with some delay. So we can still go back to the ayah that we read easier.

I hope there is no Issues open discussing about this issue.
