1) No.
2) Some people have 300sp and mad regen and would never run out, if I could mine this much faster then damn
Carry a bloody pick axe, it's not that hard. This would possibly make mining normally inferior.
3)I want a sack that looks like a present or something...you open it, put something inside..the second time it's opened it disappeared and the item you put in it appears in the person's inventory.
