It would be great to have more gather-able vegetative objects. Even if the game does not have any current use for them (i.e. "junk inventory items").
For example, the current version has weeds in it which you can cut down but you do not get anything in your inventory. Now, if you could gather things like different weeds, different mushrooms, etc (like you can currently gather different flowers) that would open the opportunity up in the future for either yourselves or plugin developers to create custom recipes with them.
The variety of vegetative content would also make the landscapes look more detailed.
I like this concept because when viewing the roadmap on Trello this kind of brings me to the open world concept of The Witcher. You see I love to gather all the different herbs, medicinals, crops and even tree saplings. Having the ability to graft some of these plants together to grow bigger tomatoes from their wild counterparts or even taming animals is what helps bring a game to life. You could build a great world and add all the great foods but it still needs the luster to to expand beyond the horizon. We like to explore, find new and exciting things, fight a dragon or even a complete a quest with some added difficulty. You gave us horses, mules, donkeys and even fishing with bandits! I'm sure not just me but many of us are very thankful for that.
At the moment the dungeons are spawning way to frequent if we go in creative one can fly straight down and find a dozen or more. The loot is often times the same and takes the fun out of exploring these dungeons. The world generation has a lot of stone, you've got stone types in the block bench like marble, basalt and many more. Give us stuff to gather please? More treasures, more plants, medicinals, and biomes to explore. The achievements I've got a suggestion: How about we successfully tame 1 of every crop type? Afterall we do find them in the wild so their yield should be lower unless farmed.
For those of us that can't handle the rain for some odd reason can you please add some adjustments for the particles in the world? Yahwho here does have a point though. Without to explore or find we find ourselves building and staying in one location. I really hope this new version can fix a lot of this.
