I hope it’s okay if I reply without being tagged! 🙂
I do almost all of my story notes (initial brainstorming, world building notes, outline, etc) on paper. I have a designated “ideas” notebook for my WIP where I keep all of my notes (which often becomes disorganized if I fail to flag important pages). I always type my synopses on the computer, though.
After I’ve finished a draft, I take notes by hand during my first read-through. Pen and paper does take longer, but I find I remember information better.
