Congrats for submitting version 4.5 to the AppStore! It really developed into a gorgeous update through the beta process!
I have just found some minor translation bugs I wanted to share with you.
If you go to "Settings->Security" you can see that some descriptions are German (as it should be on my device) and some are English.
The same is true in "Settings->Advanced".
Please look at the picture to see what I mean.
