RED Group button now audio channel button

Press the Group button on the remote to see all the categories.

The other issue with this latest update is that the blue button no longer add channels to favorites. It still says "favorite", but when you press it (after loading the list) nothing happens.
 
When working with Kodi using a keyboard (for example on a PC), if you press M, the sidebar menu opens. This is quite handy when you want to change groups of channels on a Stalker-based guide. I was referring to this.
