There isn't yet, unfortunately. I've got form-fillable pdfs roadmapped for a future update
The editable sheets open in Adobe InDesign. They're for editing the layout & design of the sheets if you want to modify or hack the game
Right now the best option for typing on the game sheets is opening in something like Adobe Acrobat. It's pretty good at guessing where the text boxes need to go. Hope that helps until I'm able to release a more polished solution!
