In WED, It should be possible to CTRL-select several blocks when in Move, Scale or Rotate mode. It's annoying having to go to SELECT mode just to do this, and then go back to Move or whatever.

Drag-selecting multiple blocks, however, works in those modes.

I like his idea too. However, it's useless when it comes to a model that is completely flat as they don't move easily from the edge-on view....
