I am the Dungeon Master for a group of friends and we are currently playing the Dragon of Icespire campaign.
I am creating a new campaign in a world of my own creation. I am really excited for it and I am putting a lot of effort into it. Tho I should study more for my college exams.
My Tools
So I am currently using Obsidian as my main note taking app for the campaign. With A ton of plugins.
If you want to replicate my setup you can follow this guide here. It's not an exact copy of my mine but it's a good starting point to personalize.
