Thank you. I hope to keep the final version free as well, but it depends on the amount of donations I get. Of course I wouldn't want to leave my generous donors hanging, but I also don't want anyone to donate for any other reason than from the goodness of their heart - I don't want donations to turn into pre-orders. So, I'm not promising anything in return if you do donate. If you're not comfortable with this, I'd suggest you wait.
