channel switching button

[Klausing]

Hi,

can we have a button or a key combination to switch to the last opened tv station?

For instance:

- i look Pro7 and it comes commercial spots

- i switch to an other programm like RTL and look an other film

- after a minute i click on this button and the viewer switch return to Pro7

- if commercial spots currently running ,i click again on this button and the viewer switch return to RTL

- so i can do it again until the commercial spots are finish

 

So i can fast have a look to the other film and during the commercial spots look an other film. (a little window with the other tv station would be wonderfull, but with the SS2 we cant do this.)
