Not sure who to contact /how to contact but here is an idea for the notebook (I have it and I like it).
If there is something written - make it a different color. I don't make notes on every hole / every shot. However, I don't remember if a hole has a comment or not so I end up wasting time and looking. If it is blank - leave it white / red / etc. If there is something posted in it - change the notebook to green.
thanks
