After making a pack, its really tedious to make any changes if you want to add or remove discs that are currently in it, I feel this would be a good idea to implement in the future

Kinda related to #30. I agree, it's definitely annoying to update an old pack with new tracks, but unfortunately it's not trivial to build a list of tracks by parsing a resourcepack.

thanks for that, ive just started doing that with my current pack. Hopefully one day we see a nice solution to this issue!

I recommend keeping your source files in a folder somewhere - that way if you want to update a pack you can just generate a new copy with the new tracks added.
