Bundles are finally on their way. They are still only in as an experiment but they are now in Bedrock edition as well.
Alas, my Derp & Chill season 2 rabbit farm isn’t necessary as the recipe has been simplified to use a single piece of leather and a single string. That’s actually less rabbit hide than the old recipe and less string too.
There is also an experiment for Redstone and Minecarts in Java Edition. Yes, they are experimenting with Minecarts. So, if you like trying new things (and hopefully giving feedback) pull up the latest snapshot and have at it.
