I hope I'm not repeating previous posts, if I am, sorry.
Although items instantly being ported into your inventory will be immensely useful a lot of the time if you're just clearing the way or removing eyesores you might cause unnecessary baggage. I think there should be an option so you can turn off/on items falling after their block being broken, so you can switch between how minetest handles it and the way minecraft handles it. Maybe even a third option which stops items dropping at all?
