Could/should there be a right-click option to remove all loose blocks.
Its a right "drag" 
to clear them up after a long debugging/editing session
I like to click clean up blocks, then I drag and drop every loose block. It's better than searching all over the scripting area to find loose blocks.
That's what I do but it's quite time consuming anyway
Yeah, we should do something like that. The other idea along the same lines is to be able to drag out a region to delete.
I think that would be a good idea!
Maybe like how you can select things on the desktop by holding the background.
i think that's what bh meant
I'd prefer cleaning them up, but this idea sounds good as well.
