As the subject says, if you've no other menu or interface open and watching a channel, when you press Exit button, it brings up at the bottom of the channel bar (where you would have normally Info Bar). It allows you to view previous and after channels and also flick thru them to move to those channels.

Really cool feature, however this channel bar is way to wide and as a result both ends of this bar is cut out. I've tried reducing width through User Interface Settings, but that has made no change to this bar width.

Any advice where can I find it?

Thanks for speedy reply. I'll check that one out once I'm home. Will post back here so everyone can benefit.

Found Virtual ZAP plugin and enabling it by selecting "Usage = With Exit Button" worked fine.

Many thanks for pointing me in right direction.
