Windows Phone is definitely a better platform after the Mango update which brought lots of features — around 500 according to Steve Ballmer — but if you still have something that is missing you can always suggest it online to Microsoft.
Additionally, you can now do this right from your phone with the help of the Suggestion Box application. It “allows you to provide feedback and make your voice heard to the teams building the Windows Phone application platform”. You can review suggestions made by others and even vote for your favorite ones, hoping that Microsoft will listen and add the bits in the next update. Grab the application from the source link below and share those ideas!
