I don't like the new setup, I liked the color coded saved notes. Each month was a different color, easy to categorize by changing the date a note was written, thus changing the months color or year saved. Instead of updating from people's listed issues, just increase the number of setting options so each person can customize their own. Instead of only being able to change the actual notepad they write on. That way they can decide how much they see, what color saved notes are, what font, etc.

Hi Stuart, thank you for this valuable feedback. Your review made us realize that new features shouldn't replace the old ones — they should coexist. We're working on per-note customization: background color, font style, font size, and more. Your voice truly shapes our app. Stay tuned! 🔒📝

Im giving it 4 stars since it does do the job. But while you're writing a note you can't see what you're writing. You can easily type the date and title but you can't see the actual notes. If you fix this I'll gladly give it 5 stars! (I also appreciate the additional settings °^°) Edit: Thank you so much! I really needed this! :D
