The number of icons is not constant.

We have 4:
Favorites, menu, full screen and page number.
Enabling translations adds an extra 1. Recitations will add an extra 1.

You can have 4, 5 or 6. How would you center the page number when you have 4 or 6 icons ?

You also don't have to go to normal view to exit. You can select quit from the menu.

I believe that the place for the icons should be fixed. We shouldn't change it depending on whether full screen mode is enabled or not. It becomes confusing to the user.

I tried the new icon and it's having the same problems

Recitations will be put in /home/user/MyDocs/.n900-quran/recitations hopefully with 1 file per aya. If you can generate such files then nothing will prevent you from adding it
But initially, I'll use a list of hardcoded recitations just to ease the implementation (Same as the translations)
