Very useful at the table to reference monsters and spells. Also helpful when designing a session. Kept up to date with Paizos OGL.
I also like the bookmarking system, which allows one to save multiple pages in a file whose name can be edited.
I wonder if its possible to include 3rd party OGL content? Akin to d20prd.
