A screenshot from an Obsidian.md vault. It shows, in the left sidebar, the structure of all the Pathfinder for Savage Worlds rules along with some adventures. The right sidebar is like a GM screen with shortcuts to combat and situational rules, basic information on the PCs, and a raise calculator. The middle (main) pane shows a location within the adventure. It has a zoomable map of the level (centred on the location), box text, and other elements needed to run that location.
Most of my prep tends to be digital as my handwriting is appalling. I put things into #ObsidianMD and then run the game from my MacBook or iPad. Took a bit of work but I'm proud of my #Pathfinder for #SavageWorlds ( #SWADE ) vault.
