Hi,
how do i place a icon in the top left desktop where for example the "New Mail" arrives?

Would be nice a snippet with an example.

Finaly I would like to close my app also with the BACK Button, but than in the Top left desktop
appears an icon and show its still active. when I open the info window (like "new mails arrived) and
click on the symbol my app should restart.

I know.. that would be a lot for a tutorial.. so I am happy with just the first hint.. how to add an icon
in the top left desktop

thanks
chris
