Each inactive button has a description of its function in the VIP version. So the real question was: can Dazzel add those new functions in his own app?
I would never give a penny to someone who is twisting the sense of the word "donation". Offering a product for free gives you the legitimacy to ask for "donations". But conditioning your product with payment - that is not "donation" - it is buying and selling. And if I want AND afford to buy something I would do it from whoever created the game.
Keep waiting for v.3...
