Not much to show, I just use a ringed notebook for noting down things that happen during the game.
I've found that I prefer A5 format. With A4 it gets big and by the time I get to the bottom of the right page, the notes at the top of the left one are ancient. A5 is easier to manage
I prefer systems where I don't need so many stats. Savage Worlds is the most crunch I can work with. So for the plot I only need a way to check up on ideas and "arcs" and for that I use ObsidianMD on mobile or PC. I'm jumping around different topics a lot, so even having bookmarks in notebook would be hard to work with
