Need your inputs to create the most useful printable day planner/journal

I am learning to generate dynamic PDFs on server using NodeJS. So I decided to create a side project and build something useful while I am figuring the technical complexity involved.

I am planning to build a free printable and customizable day planner/journal that people can use to print and use.

Here is a mockup of what I am planning to build

This will print on an A4 sized paper and will have sections for

• Memory journal
• Gratitude journal
• Goals
• Top 3 tasks for the day
• Other tasks for the day
• Tasks for future
• Habit tracker
• Notes
• A motivational quote at the bottom

I am trying to make it all customizable so that you can tweak the labels, habits etc and get ready-to-use habit trackers.

Although it is a side project and will be free forever I want to make it as useful as possible for all of you.

• What would you like to customize in your day planner so that I can add those customizations in the app
• What items would you like in your day planner
• What habits do you track so that I can put those options in the customizations
• Are you using any day planner? Can you share a template of what you are using?
• Any other feedback to make it useful for you

Thank you in advance for your feedback
