It is great that you now can write to the calendar database but there is not any API for change or delete an appointment?

The TileSource class enables developers to provide custom tile sources for the Bing Maps control (such as OpenStreetMap), but requires an absolute URI to provide tiles. Given the frequently disconnected nature of WP7 applications, it would be better if it was possible to provide tiles from isolated storage to enable map downloading and access to maps when offline.

a separate volume would be perfect as it allows to handle the volume of an app much more simply.

Add a Textbox control for the ApplicationBar like in the Internet Explorer.

it would be helpfull to have a passwordBox like control which supports Number only keyboard. Numeric only passwords makes more sense for Smartphone world as its fast, convenient and easy to type.

If my users want to move through a song a little bit, there is no way to do that, as MediaPlayer.PlayPosition is read only! Should be able to set it.

Please show the scrollbars in the WebBrowser control. For details and a workaround that's not working as smooth as it is when it was implemented in the control itself.

To support things like midroll video advertisments, multiple MediaElements are needed. This is supported in Silverlight for the web.

Currently you can assign to ApplicationBarIconButton an icon present on your project as 'content'. This basically means you have to determine your icons at design time.

By providing the ability to assign an icon placed on the IsolatedStorage, the developer will be free to create button icons at runtime, dynamically download them from other places etc.

Would be nice to have the possibility to set background color, icon color, etc. not just hide or show.

Allow the user the option of choosing a non qwerty keyboard layout, as a full keyboard can be really frustating at times due to the small keys.

I understand the max size limitation to control. And there are some approach to work around on most of the controls. However, for some control, e.g. TextBox, it's a big problem.

Provide a viewer for viewing office documents (e.g. word, excel and powerpoint basically). The UIWebView in iPhone support serveral formats and give a very good user experiences in some content related apps

Font weight in Button is not working at all.

Increase webbrowser control

Please allow the access to Gmail's Todo list sync when a google account is added on the windows phone. Under calendar I see the todo list of hotmail and I like it, it would be great if I can add the gmail's ones too and have the ability to make changes when sync happens or just have the ability to add todo items and those get sync to the phone.

We need different sound levels...sound level for system, for alarm clock, for music-radio, and different for keyboard.

I want to have sounds enabled to keyboard but not at highest level, also i want to listen to radio (throuth the night) and be sure that the next morning the alarm clock will sound as high as possible to wake me up.

I hope you get the point !!!
