There have been numerous major bugs and lack of features that are taking just too long to update. If Windows Phone as any faith in its future it needs a lot more support from the development team. Bugs like the "other storage" have been there too long and only get fixed in annual updates. They should have been fixed days or weeks after discovery.

The delay not only has a impact on phone users, but also on the developers building the apps for the phone when the bugs and missing features impact the user's app experience.

Mark sideloaded apps in app list so one can differentiate an in-store app from a side loaded version that's in development.

We need images or iso to test first the new version of windows phone, something like apple make with ios. This is good for helping MS to close bug and it's good for us to test the apps. This can be an easy thing because the phone have the same hardware platform.

Photo chooser should also allow us to customize the photo chooser task like the one in Photos Hub. The photo chooser task needs to support selecting multiple pictures feature, and add an app bar to it.

Make the logic of the MapsDirectionTask equal from the one used within the Bing search. In fact in the second case the "directions" toolbar start the navigation app while in all the app using MapsDirectionTask the toolbar button of the same name let the user go back to a previous page asking dor start - end point, while the launch of a navigation app is made in done by a different toolbar button in that previous page.

I think that it is not nice to give a different user experience.

It's annoying having to download and install the toolkit separately.

BingMapsDirectionsTask, Only set start point, when the task is running, it's prompt "Getting directions" , it's alert "End point not found, we couldn't find a match for your ending point."
I don't think this is a good design for BingMapsDirectionsTask, it's not flexible.
i cloud be only set the start point or not.

The MediaPlayer class can play Song objects, but there is currently no way to get at the song data. Allow binary access would allow custom vizualizations, media players, and audio enabled games.

This would also solve another requested issue where devs want to get visualization data. With access to the song binary, this data could just be created by the dev.

Add a full support of RegionInfo and add possibility to instanciate one with two letter iso code.

SO, we can use it to dispal country name with user language.

with this mod we can enjoy the platform more the than ever before is to make in the landscape like the upcoming windows 8 or like the original tile home screen from up to down or down to up

Return back a multi-task support (may be optional?) will significal improve advanced users experience. In current situation its almost impossible to create some kind of applications, such as different trackers, survilence etc

QRCode should support chinese

It would be very nice to be able to download the entire Windows Phone Tools and install it, instead of having to use the web for installation. I am a teacher and having to install it this way for the entire lab takes forever.

There is currently no way to know if an EmailComposeTask was cancelled or got an error while sending. I need to be able to tell if the user actually went through with the email to know whether to delete the email text. Otherwise I have to ask the user if they sent it (poor user experience).

The implementation of the SQL Compact was a pretty steap learning curve for me as i was used to the .net GUI Implementation that made it very easy to use. I think there needs to be more focus on making it easier and quicker to implement these plumbing features as a lot of developers will be hobbyist and do not contain the time and knowledge required to implement of lot of these plumbing features. Please make it quick and simple for us to get our ideas out there. Detailed customization should be an after thought for us

We can access exif info (limited) using a Picture object when dealing with Media library. But if we try to save an Image within app inside Media library or some Isolated storage we can't prserve exif info of that image. A better manipulation of exif APIs will be very helpfull.
