These are my ideas after a quick use of good notes (Lots of desired improvements but great start)
1) Use a slide as a way to choose the size of the pen/eraser, or at least add 2 more sizes to choose between
2) Delete comments
3) Use your fingers to move or resize lassoed notes
4) Use the keyboard to type notes
5) Shapes and Coordinate Axes
6) Ink to Shape and Ink to Math
7) Look up handwriting to find documents
8) Insert PDFs, documents, or images to write on
9) Record audio from class
10) Better exporting i.e to PDF or straight to email
11) Pen and Highlighter groups so you have a preset group that has certain sizes and colors
12) Change the color of already written notes using the lasso feature (should be able to do this using your finger)
13) Allow the use of tabs like the Ipad version
14) Use the half-window preset that Windows 11 offers
15) Variability of line thickness based on the pressure of a pen
16) Folders and Organization for Notebooks
17) Insert or Remove Space (like onenote)
18) Ability to view notes on the phone
19) Share, favorite, and even collaborate on notes with others (cross-platform as well)
20) Handwritten flashcard set!!!
21) Laser Pointer
22) Make the hold-down time to interact less to get to copy for example
23) Much better notebook interface
24) Settings menu
25) Make it as similar to iPad as possible but take advantage of the high power of windows and laptops
