I love the spring cleaning challenge, what can we do after the 14th?

I’m one of the people who absolutely loves this new addition to the app. So much that I’m sad it ends on the 14th! For the other people who love it, could we start a list of things that we could do from the 15th through the 31st that are in the spirit of Spring Cleaning? Once there are suggestions, I can create a list of additional popular daily challenges that people can add as tasks if they would like.
