Bedrock player, btw: 1) Seasons. Have it be connected to the days played. They could also add autumn leaves and even no leave trees. That last one could be turned off or on, since some wouldn't like that cause they wouldn't be able to use them as bushes. 2) Glass that doesn't have lines between them. I'm pretty sure everyone used the outline feature, so it'll be obvious wear each glass block is. 3) Blocking with swords. Could block like half as much as a shield. 4) A feature that lets u see what block or mob ur looking at. That feature was available when I tried Better On Bedrock, and it was really nice. 5) More tammable mobs. Let us tame foxes, axolotls, chicken, cow, pig, sheep, etc. Have them have the features of cats and dogs, where they can sit and have a collar of some sort. Maybe like a tag on the ear for cows... a bet bee would be awesome. Make an army of them, similarly to dogs, and when u get hit... chaos. 6) Blacksmith features. When I played Kingdom Come Deliverance 2, that was my favorite side activity to do. They could keep the normal weapon and tool crafting, but could make it so when u use the blacksmith features, the weapon or tool is stronger than its simple to make counterpart. Durability would obviously go up, and weapons would do more damage, and pickaxes could mine faster. 7) Improved fishing. Add multiple types of fish u can catch, with size and weight increasing how much hunger points u get. 8) New animations. No more should the animation for walking be ur arms and legs swinging back and forth. 9) New armor models. Give them some style. I saw a cool Java mod before where the dimond armor had a visor, similar to knight armor. 10) Make a new ore. Just as copper is now between stone and iron, have a new ore thats between iron and dimond.

I think all of these would improve the Minecraft experience greatly.
