Hi, I've been through the tutorials, and it completely skips over how to open the table top editor. how do I get there from my home page? I can figure out how to draw and add things if I could just see how to open it. On the compendium page, it gives options for DnD5E or Pathfinder. Must I choose one of those; Pathfinder since i am using 3.X edition rules? How then do the rules from pathfinder affect the game itself since I am not using Pathfinder rules.. or am I? Thanks!
