I love almost all the ideas you outline here. I don’t know why you insist on calling your project useless, and hope you’ll execute these ideas.
Ha! You’ll notice this one actually says “Useful.”
I think “my” project would benefit greatly from your help with some of these. (“My” in quotes because it’ll be tough for me to spend any length of time on editing, given my life situation now.)
Certainly having another edit to look at will help you see how you like concepts in action.
