In my opinion this would be a good addition to the epg as long as it is configurable.
On Humax bxr hd+ one of the few good things in the gme is that pressing the ok button will zap if the current program is selected.
Having to press the red button to zap when in epg has annoyed me ever since I got my first dreambox some years ago.
For some strange reason I'm never getting used to it :-)
