Here are the Minecraft suggestions I have posted on Reddit. I'd like to hear your opinions on them; you can either post here on on Reddit (but preferably both) :).
The world spawn should not occur in deep water or lava most upvoted
When shift-clicking items from container into inventory, it should appear in first available hotbar slot
There should be a way to fly without double tapping the jump button
Wrench [Rotates Blocks]
Sweep attack should only activate when holding a certain key and not going faster than walking speed
Custom Mob Targeting
Non-creative mode players and non-ops should be able to view command blocks
Desert Temples should spawn with torches in the treasure chamber
