Known issues you would like to see addressed in future firmware updates

There are several issues that need to be addressed. My most important issues are in the following order:1) Fix the accelerometer. I bought this tablet for a lot of things, but one of the most important is to play games like PapiJump and Labyrinth.2) Add Market Place. I don't want to have to add a script every time I upgrade.3) Add a sleep feature. When the screen gets darker, it never goes totally black.3) Fix the buttons. Make the volume buttons work, and the big button make it sleep.4) The battery level indicator. It always reads 100%, no matter how low.
