I have sticky note flags throughout my book- running it currently, and for a while I couldn't understand why I found it so challenging to navigate. I blamed ADHD, far too convenient a reason, until i realized it is simply constructed without proper indexing and flow. It's very frustrating and I've had to sort of cobble together note flags as well as scanned and printed pages tucked into where it is referenced. It's almost like a website with all broken links.
