I'm sure this is nothing earth shattering, but I think it's pretty cool.  I've made a "nested macro" that links to other macros for light sources and the Darkvision and Low Light Vision abilities.  The macros require " TokenMod ".   I'm excited to try them out. My players can have appropriate light sources and/or abilities and the NPCs can as well.  With a simple Ctrl-L I can see what any given token can see.  I think it's going to make things like a potion of Darkvision or Dancing Lights much cooler.   Here's a link to a text file on my Google Drive:  Light Macros.txt
