1.26.4 possibly?

Leather tanning, a new resource, this would require adding 2 items to them game, a tanning rack and a scraping tool (maybe make it out of a seashell? Might be cool). To tan leather you lay out maybe 2 or 4 on a rack, you could have a mechanic to stitch them together to make shapes with string, on the rack they need to stay out for a day or two, you also need to scrape it once then leave it for another period of time. With this new tanned leather resource I think at least horse armour and saddles should be made of it, it would add back some of the previous value they held. but along with that a new item and a revision to the straw bed, the backpack+nightroll (both made with a fair bit of tanned leather) is a natural and based in minecraft technology that has excellent utility. While the shulker box does increase inventory capacity it doesn't improve your inventory space. I find tools clutter my inventory with a mace, a spear, a trident, a whatever, with 12 maybe 16 spaces in a back pack that perhaps takes a second to open but is directly in the inventory screen and can transfer a bit of inventory would be a great update for the current state of the game. To travel to all these new biomes youre making the trips can take days and phantoms are defintiley my least favorite addition to the game. That is all, thank you for your consideration on this matter if anyone of relevance does read it, pls pay me I have more good ideas, been playing a lot recently
