I leaned into it last couple of years, I have a 2 corkboards (a bit larger than A4 sized) on the back wall of my desk and I actually mounted a stationary clamp under one to have blank papers (A6) handy. It works pretty well until I fill them and move on to another notebook scrap paper etc.
I wish I could stick to a notebook and have everything from each time period but I have too hectic thought process I think. Maybe I could somehow combine them...
