[James Falconer]

What does everyone think are the best features of Windows Phone 8.1? What features do you wish were available in Windows 10??

Battery life, stability, having a black navigation bar no matter what and that Lumia Camera! I miss being able to use the light theme and have a black navigation bar together, which is something I wish was available in Windows 10 Mobile. Additionally, I wish that we were able to have the weather app on the lockscreen again. I loved being able to pick up my phone and see what the temperature is, along with the weather for the next few days.
