Flags:
This would go with maps. They would appear on your map, and would be able to be dyed a different color to determine which flag is which. They would be made with 3 sticks and 4 wool:
[S][W][W]
[S][W][W]
[S]
S: Stick
W: Wool
Destroying Items:
Ever want to just get rid of that Wooden Pickaxe without dropping it in lava, or leaving it somewhere for it to despawn, giving you the chance to just pick it up again? This would solve that problem. There would be a Garbage Can icon in your inventory which, when an item is dragged on to it, would destroy that item. To prevent accidentally destroying your Diamond Pickaxe when you are moving your items around, there would be a confirmation box, which would automatically appear unless it is unchecked in the Options menu.

Also it's one suggestion per thread.
Just incinerate your tools in the lava...
