I designed SickSky for phones and not for tablets. The problem is if I allow it as compatible with tablets on Play, then a lot of people would not be happy with how it runs on a tablet (ie no landscape, no tablet-specific layouts etc). Anyhow it is still in beta for now.
Wait, are you simply ignoring the HD2?
It has been a good couple years. For now I am going to focus on building panels to suite most needs. Next up will probably be a shortcuts panel. Not impossible to add widget panels later on, but going to stay clear from that for now since I wouldn't use that myself.
