customer URL and backup/restore DB are great, and requesting usage reset button.

Usage meter isn't necessary for me; however, I know it may be useful for some other users.
Here is my idea: add an option to user to enable (default) or disable usage meter.

Oh... wait I think I'm lost... Are you talking about the meter on the widget? If you are, this shows the realtime internet speed.  So if you see a lot of buffering and you look at the meter you will see is low and orange.

This is different from the widget.
On the main screen, go to settings and scroll down to see "lifetime streaming stats".
I don't need this stats as my mobile internet is virtually unlimited and I don't worry about it, so I suggest there's an option to show (default) or hide this status as well as letting the user to reset the meter.

Ok, now I understand exactly what you are talking about... :) The feature is there more to let you know your streaming stats.  I didn't implement this as a mean to keep track of data usage and costs... I thought it was just a cool statistic to have.  I can definitely add a reset button to those stats but I don't think we will remove or hide it...  Why do you particularly want this information removed? I assume that if you don't care about data usage than this information wont hurt... :)
