Obliterate!

[JeanDeaux]

Are there any mass deconstruction tools available? If I wanted to deconstruct everything in an area, I'm torn whether or not I want to keep the resources. It's more effort to deconstruct and stockpile than it would be to simply make everything go away and start over.

I know about holding down Left Control to select multiple items for deconstruct, but that's a 50 item limit. It's helpful, but I want BIGGER!
