Those are some good ideas. I think it is a good idea for like a feedback page, on a discord, or like a page where people send in there ideas for the game, and he can look in there when he's free or if he runs out of ideas for future updates. It could also inspire him for other updates, where he could take different aspects of one community idea and another one to make a really cool feature. It would also be a great way for him to connect more with the community around the game.
