Me and my buds are gonna do a thing where we make resource packs and then switch with each other, and this program really helped me prepare a complete 1.15 default pack template for everyone to start out with. I had everything else, all I needed was to extract all the sounds somehow without doing it manually, and this little program is exactly what I was looking for. It was very user-friendly. And yes, it still works on 1.15. Big thumbs up from me!
