I agree that the parent coaching application sounds interesting. I agree from what I have heard from teachers and administrators from several districts that virtual learning is here to stay. I know your situation with younger learners is quite a bit different from my experiences. The IT staff in our district created a website for Parents this year. Maybe you may find some inspiration here!

I love it, this is super helpful - thank you! I feel like our district put out a lot of information and videos but it was not all in one helpful package like this.
