As of this moment I’m not planning to add support for hex grids, sorry. 
I may succumb under popular demand, but for the time being I want to focus on square tiles. My goal for now is to perfect it in terms of providing easy access to any positional info that high level AI would want. I bet you’ve already seen Monokkel’s plugin announcement, who did a great job on hex grids. If not, you should go check it out.
Edit: I updated the first post to include a video of the plugin in action.
