The option for infinite pages like Onenote would be amazing! I find being able to scribble out ideas for mind mapping really helps me with my ADHD.
The ability to print it out later would be great as well, perhaps in the form of light outlines in the background on the template so we can visualise where all of the writting is going, or an auto suggestion?

I love how CollaNote allows you to have multiple pen/highlighter options on the side of the page instead of the top bar. That would be reallly really helpful as well as I colour code my notes.

Lastly, the ability to quickly convert handwritten notes, text, or PDFS into flashcards would be really cool. Maybe being able to select a section, press a button and it converts into the format? Something more streamlined than lasso, copy, paste, resize.

I also find that I often accidenty change sizes/move text boxes around.
Being able to “lock” in a text box (or even the pen tool) so it’s set in the background would be so useful as well.Idk if that option already exists and I haven’t figured it out yet. Being able to dupliate those permenant structures to other pages (like a template) as well would be fantastic

I find these things could really make a difference in my adhd uni life brain
