Enhancement Request - Horizontal/Vertical mode & block blacklist

[ariosos]

I'd like to see settings to veinmine in horizontal and vertical modes along with the radius mode. There's a lot of times where I just want to remove a few layers from the top of a hill. Also, a block blacklist would be nice, too.

Most likely not modes.

Maybe blacklist.

Please, I beg you, implement a blacklist!! I've spent hours undoing the damage from accidentally vein mining stone, and I'll probably have to spend a lot more until there's a blacklist for vein miner.
