This (forge) mod lets you mine giant areas of blocks at once! (config values for size.)
Left click any block with the miner item to switch modes (cube->cylinder->pyramid->cone); Rightclick to actually mine stuff. All items go in inventory first, if theres no space left, it drops it on the ground. Items that dont fit in the inventory get deleted in creative mode.
If in survival, using the tool consumes hunger per operation (config option.)

I also stream some mod dev and a couple of other things every once in a while: Twitch
