Add support for the biometric framework from windows 7/8 to allow hardware manufactures to add fingerprint sensors for device login (login allows standard user & guest/kid mode) and for wallet (WP8) transaction activation.

Remove the 50 apps limit from the phone and 100 app limit from the marketplace web site when users search for an app with a search term. If an app can not be found with its ideal keyword (becuase over a hundred apps already have used that search term) then new apps cannot be found with their ideal search terms. The concept of paging using skip and take very easily resolves this issue. It's quite dissapointing that a Bible app cannot be found with the search term bible.

the most apps in the marketplace are ugly and not like ios or android.

WiFi calling allows people to call/send messages over WiFi rather than cellular signal. Knowing that you don't get signal everywhere that should help.

I would like to be able to promote my app for a certain time by reducing its price (e.g. during holiday season). I don't want to create a new app release for that reason. So please decouple app releases from the commercial stuff...

It's currently an inconvenience totalling individual download totals to discover how much money MS owes to developers, it would be nice to have this information automatically calculated perhaps with a date and total of upcoming payouts.

we want an official yahoo messenger to be developed please.

Currently, you can only have the review page from the app list with the contextual menu.
It will be pleasant to go the main page of the app in the marketplace to see the general présentation, screenshots & the other users reviews

I would like Zune to be capable to play as many movie file types as possible. Just like VLC Movie player is.

Allow platform built-in camera and video apps to use increase and decrease volume hardware keys for picture optical and digital zoom of camera. On WP8 add optional support to hook these hardware keys press events for the lens (plug-in) features...hardware keys should include vol+, vol-, stage 1 (light press) camera shutter, stage 2 (deep press) camera shutter.

Equalizer for Zune for example bass and trebble enhancements

The excel file is cumbersome to use due to formatting and scrolling issues with large cells. It would be nice if the app hub could, in addition to letting you export to excel, just show the crash reports on the app hub using formatted html, and have the stack trace formatted to be readable (not all in one line).

I haven't credit card to pay $99 USD just have in cash
