Pens, Pens, and more Pens. Chistle tips, calligraphy, glitter. There can never be to may pen and highlighter options. So many programs have tons of pen and brush options. OneNote 2016 had more than the current versions have. I wouldlike all versions, but escpecially mobile/android versions to have calligraphy, glitter and brush options. I use OneNote as my planner for work and family life and would like to be able to write in different ways to help deliniate things without having to leave the program, make "word art" and come back.
