-+ =+roam= Enables org-roam integration.
++ =+pretty= Enables pretty unicode symbols for bullets and priorities, and

 Org has a few soft dependencies that you will need to make use of Org's more
 esoteric features:
 
-+ For inline LaTeX previews, you need ~latex~ and ~dvipng~.
-+ For rendering GNUPlot images (with =+gnuplot= flag) you need the ~gnuplot~
-  program installed.
-+ To run babel code blocks, you need whatever dependencies those languages need.
-  It is recommended you enable the associated =:lang= module and ensure its
-  dependencies are met, e.g. install the =ruby= executable for ruby support.
