Thinking of suggesting something? Might want to check the list below for some things that frequently show up both on Discord and here.
Note that the list does not include things that are already planned in the Roadmap. Please note - Unless otherwise noted, this is not a list of things that will be added. Just things that frequently show up.
The list is subjective, non-final and I don't comb the Discord for these, just update as I notice things being repeated.
Worldgen and Mechanics:
Oceans, rivers and seas - Including saltwater.
Boats and other vehicles, including carts. Also multi-block ships.
Taming animals and mounts - The former is in the works and there is a basic implementation of it.
More limestone/chalk generation
Making farmland drop soil
Combat, Armor and Tools:
Gear Repair: Comes up very, very often. Whetstones and sharpening for tools, repair for armor.
Shields / Combat Revamp
Blacksmithing leftovers and broken tool scraps.
Crafting & Cooking:
Tofu and more ways to use soy beans
Making sticks out of planks
Freeform cooking - Ie mixing meat with rice and such.
Steel - It's coming, shush.
Kilns and proper ovens.
Player Customization, including custom skins
Removing the crafting grid completely
Steam, the client, not power.
If you're looking for mod ideas, consider Lazy Warlock's thread, too.
