I personally would suggest the mod called bullseye even though it changes how base game ranged weapons work, I find it more fun and rewarding. There is a link to where you get mods on this very page, at the top where it says "mods" but it leads you to https://mods.vintagestory.at/.

I would imagine it either was a mod or, most likely, you had a 2nd copper pickaxe. When a tool breaks it gets replaced with any spares of the same type (even if they were made of different materials).

If you go into creative mode, and hit default tilde(~) key you get the world edit options. On the panel on the right there is an option called block picker range or something like that. If you change that you can increase or decrease the default range.

With the gear moving back and forth, unless someone knows more to correct me, I'm fairly certain that the idea is you are in a zone which has maxed the gear out and it is simply animating for the sake of animating rather than saying you are losing any stability. If it was only moving down, and you mouse over the gear to see you are losing stability then the area is unstable but you should be fine there, as far as I know.

Without knowing the code or anything like that, including what version you're on, I seem to recall that not so long ago there was an update to fruit trees to stop them from resetting their progress to 0 when the player is far away and unloads the chunk. I would imagine that while that may or may not (I wouldn't know) have been fixed, being away from the trees probably doesn't reset them now, but might stall their growth progress. That is to say, consider sticking around in your base for a while longer to see if that fixes it.

If you mean you want to put voxels you removed when chiseling back you already can do that. You just need to right click instead of left click when looking at a portion of the block that's still there. (As in you can't put stuff back by right clicking on another block.)

I personally hope it does make it into survival, but currently its sort of pointless. Right now, if you equip the quiver it has 10 slots like the mining bag, but only holds arrows as far as I can tell. I don't know about you, but I have never had more than maybe 3 at most stacks of arrows in my inventory, usually I only have 1 or 2. Ideally for me, the quiver would be something that goes into a new slot, possibly a belt slot sort of thing, which maybe can only have a few kinds of items worn on it like possibly a scabbard but I don't know how best that would be implemented. The quivers capacity could possibly be reduced from 10 to 5, and it would still hold value as possibly being a large pvp server item, without being a big drain on the users inventory capacity by taking up a backpack slot.
