2. Don't know much about widgets. But If C series could make it work, that B series make it too, of course in theory..

There is already widget what can check Gmail box for C series create for Samsung TV Challenge

But no download for now


Maybe contact with author for it

Hey, there is another interesting app - PcRemote - and executable for it.
Oh, here isn`t any widget to download...

geo650 shows that we could put OSD pictures to screen, right?
Why don't we use that SDL functions to make similar application for B series?
With it, I think we could port libnotify daemon to TV, with beautiful graphics and could watch phone rings, mails...etc from it.

Integrated notification system is not so beautiful.
