Facebook App for Windows Phone

I generally like my Nokia Lumia 920. It is a great phone, worthy to be spoken in the same breath as the Galaxy and the iPhone.
I do have a minor gripe concerning the Facebook app. It is a bit confusing to navigate at times. There should be search feature on the main screen. Instead it's buried within the "Friends" section on the users profile.
I believe the whole app could have been designed a bit better.
For another example, why couldn't you chose a banner picture from a selection of posted photos, instead of constantly selecting the "change banner image" over and over?

These are just minor gripes.
