Allow developers to implement an interface(s) on a user control and "submit" that instead of just filling in a tile data structure. This will make tiles truly "live" and open up the live of WP7 to new applications. This is also completely secure because the runtime can analyze the class (and it's IL) being submitted. A bevy of restrictions can also be heaped on the said user control in order to maintain performance and not sap battery life. Let Live tiles be live, please.

When you create a tile dynamically, it is common to want to save it as a Png file so that it uses transparency (so that it respects the theme accent color).
However, there is no built in method to save a WriteableBitmap as a png.
There is however a nice extension to save it to jpg, but that doesn't help if you want to use transparency to leverage the theme accent color in your tile.

I think many apps that need to generate a tile dynamically will encounter this issue.

Scheduled tile updates should not be canceled due to lack of network connectivity.

Currently, after losing a signal for a while, tiles stop updating because the maximum of three failures has occurred while no network connectivity was present.

After network connectivity is re-established, the tiles never update again, even after several days of good connectivity.

Instead, the tile update schedule should be resumed after network connectivity is restored.

Currently,we can CREATE/UPDATE a ShellTile using a ShellTileData,but can not to get ShellTileData from an existing ShellTile.

Please release ShellTile.TileData() function in next build.

There are some apps which simple are needed but not needed for quick access. Like Adobe PDF Reader or Phone Settings or development test apps. My idea was to add any group like already available for contacts to sort and categorize apps. In that case every user can choose which apps are important to have direct access by tile or which are in a minor priority or which have very less priority to have direct access to it.

If I want to update a Live Tile from my own App I can't draw it's background image on the phone, because if I store it to IsolatedStorage i'm not able to get an URI for it which I could provide the StandardTileData-Object with.

One vital feature I truly miss is the availability to create custom category hub tiles. Since I've downloaded tons of handy apps from marketplace it is getting pretty hard to find the apps since i sometimes forget their names making the A-Z list more or less useless. The lack of categories truly bothers me. The feature doesn't need to be complicated at all really. Just a simple UI similar to the A-Z list you get with WP7 out of the box, but with the apps of your choice in it. Great community WPDevs! Thanks in advance & for amazing OS!

In short, now that we can have multiple tiles, sure, it's great that they can open the app. But why not let us flip the tile instead (Note: The mail tile would *always* open the app.) Think of a 'Stocks' app where you see the price and change on the front, then tapping it shows the graph on the back. Perhaps a double-tap opens the app like they do now.

At the moment there's no way for an app to know if its primary live tile is visible or not. As half the point of my app is the information on the live tile, I'd like to have a polite reminder show every so often if they haven't pinned it, but I simply don't know whether they have or not.

Want to be able to have small rectangular tiles on home screen, rather than only tiny/medium squares or huge rectangles.

I suggest having an option like (UnPin) on any live tile to (Update) it. With feature user can run background service to update live tile when he need which can help developers to give instant feedback on live tile when user request.

Of the six Tile properties, ShellTileScheduler currently supports only scheduling a change to the BackgroundImage. It'd be nice to expose the rest of the Tile properties.

ok so sick of evry thing else turning but the home screen just make it turn so easyer to read and a place to report achievements not working since i have had to restart kinectimals 3 times

With the introduction of Outlook.com you now can have both Outlook.com and a corporate Outlook account synced to the device. The tile icons looks the same (as well as the lock screen notifications) and it makes it hard to make the apart (especially when I use the smallest tile where there is no tile title).

My game icon was designed to have a transparent background, but when I published it and saw it listed in the Game Hub, the transparent background was not filled with the user's theme color as it would have been in the app list or when pinned to the home screen.

Please add support for icons with a transparent background in the Games list.
