Live Feed - An obvious one, hype would be created all over social media
App Voting - A necessity in any tv show these days because come on no one spends money on tv show voting anymore so it would give the eviction a better day instead of the vote being controll by the fb ladies or the fans (eg savannah which am not complaining about but you get my point)
Cast - Like Greg said have a mix of everyone, BB19 had a good mix on paper yet none brought entertainment so make sure every single housemate selected is not boring
Structure - BB19 & CBB22 improved a lot but there was still a lot of changing
International elements- The CAN/US format could be experimented on a week and see how the public react to it and if it works make that the format
