While I'm on a TTRPG post binge, I figure I'd share a tool I've been using lately. PureRef is a reference organizing tool, which is great for doing things like moodboards and such, but it can also double as a Digital GM Screen, if you're using PDFs. I use the Note function (Control + N) to make section titles and start dropping in screenshots from the book that I need.
You can zoom in with the scroll wheel, move the window by holding right click, center click pans your canvas, and resize/move with left click. Makes a pretty useful tool to have up if you need to reference a lot of things.
