 # Battle Map TV

+Display battle maps for TTRPGs on a tv or monitor that lies flat horizontally on your table.
 
-This Python application aims to do one thing: quickly show an image on your secondary screen,
-in the right size and with a 1-inch grid.
+No more features than needed: just show an image the way you want. Optionally add a grid, initiative order and area of effect shapes.
 
 For GM's with little time or who improvise their sessions: much easier to use in-session than a full blown VTT.
