New Minecraft redstone features

Item splitters already exist but I think they're bulkier. The pot version could work if, when you're down to one item in the pot, you lock the hopper under it to give other items elsewhere in the top container a chance to go through. Just a couple ticks pause should be enough.

You can use it as a payment input in shops. Keep your redstone potato-free, and you can even label it by putting a diamond sherd on it! A label without obstructing the interactable area.

A single slice of a item sorter. With nothing in the first slot of the top hopper and an additional dummy item. A water stream pushes the items in a loop above the "sorter" to group items. Then your contraption separates them in different shulkers.

THAT sorter is what grian needs,cuz we know he won’t use a standard item sorter, but this would sort out his chest monster while keeping the shulckers

The item splitter you created is actually extremely useful to increase the speed of automatic sorting systems (they did exist already but your design is way simpler). Without splitting, you can only dispense 2.5 items per second into a sorting system due to hopper speed, but if you split the items and for each type of item dispense 2.5 per second multiple slices of the sorting system can run in parallel because any single type of item will only be dispensed at hopper speed (assuming that there is a workaround to the item order issue creating multiple shulker boxes for the same item; for this use case there might be some method like before beginning to unload a shulker box checking whether the item is already being unloaded, perhaps using more pots).

I also think that pots could be used for lag-friendly downwards hopper chains. You could alternate pots and hoppers, so only half the blocks are hoppers, so less searching lag, and its better than droppers or chests for example because it only has one item slot for the hopper to check.

I still think trap pots need to be a thing. Basically if you break it while it has TnT, lava, fire charges, splash potions, water, or even ender pearls inside they end up activating immediately upon the pot breaking. With each doing what you'd expect, including ender pearls immediately teleporting you back to the pot in question. Very, very multiplier or restone railway centered use, but I think it'd be cool. At least that use would end up playing redstone's ability to give you quick transportation and set up horrible traps.

Can't wait to see what mumbo does with the new auto crafter....saying that just makes me think of modded minecraft

It would be cool if they could generate naturally, and contain stuff like torches, arrows, emeralds, etc. Edit: I was indeed inspired by Zelda AND Terraria Edit 2: I just realized this could also be done with a datapack!

My first thought was to use the pots in a super smelter that uses hopper minecarts for item distribution. Currently there isn't a way to get exact stacks of items using signal strength; you're always going to get a little over or a little under. With the pots, you can use this system to lock them until they fill up with exactly one stack, then unlock to add them to the hopper minecart for distribution. No overages, no partial loads, guaranteed perfect distribution for fuel usage.

The pot actually seems perfect for mob grinders with item storage; since the comparator's power level can detect unstackables, items that you'd want to store/dispose of separately from the main materials are very easily distinguished!

sorting items at a raid farm. More compact and organized storage, it might work there, if you can get it to fill the shulker before breaking it.

Hear Me Out: Have them spawn in desert villages, desert temples, jungle temples, monster spawners, and trail ruins. They'd contain more than one item, but it'd make more sense in naturally spawning places. On an semi-related topic, sniffers should sniff up fossils, bones, and more flowers. Adds to archeology!

I would love if they also added a new pottery sherd that allows you to craft a pot with a little window on the side so you can see the item inside. Not only would this look really cool (especially as an alternative option to item frames) it would also be useful for anyone using pots in redstone contraptions so they can see what's already inside :)

I think the shulker storage would be useful for massive builds! If you're working on a mega structure with tons of blocks, having them all separate into different shulkets would be really useful for organization and keeping track of resources!

The shulker thing might get rid of the need for item sorters entirely for mixed-item farms, as long as enough shulker boxes are provided... and each chest doesn't "block" an item from getting in - like, if you have an industrial district, at the moment, you need a bulky storage system even for items you want to carry by the shulker, meaning you need to sort the items first, then come there with empty shulker boxes and fill them. Now, you could use the new pots to fill shulkerboxes immeadiately, then just grab the boxes you need out of bulk chests. Now to think if there is a way to sort shulkers by type and you get a storage system that only needs one shulker loader upfront instead of one for each item type your industrial district may produce... If the stack order thing can be solved, that is...

One idea i've been exploring is using the pots as a payment method for an automatic shop, sending different items depending on how many diamonds are put in.

Rather than drain the pot when it's full, set the lock on a timer so it's pulling more items while draining the pot, then when the pot gets down to a certain level (because there's no more items in the source chest) the feed closes, the shulker box is switched when the pot is empty, then the feed is opened and the drain is closed. Repeats for next item.

Now we got autocrafters, I already know Mumbo will love it.

You should be able to put double tall plants into the big pots just like how you can put small plants in the small pot
