The ability to add reminders/ notification when adding things to a planner. As well as adding how Persistent you want the reminder/notification to be. Feature I haven't seen anywhere, and I think not only would it really help people with adhd like myself but having that ability would just be a really cool feature. The way I sort of like see this working is like having it not pop up while you're using that app but outside of the app which would remind you to go look at your planner or do what you wrote down.
