besides having some way to 'preview' an item before you click on it, (which is easy enough to delete it once you make it appear), It would be awefully nice to have a way to delete an item by right-clicking on it later. There is features to edit, or 'Move, rotate, and scale,' but if there was a delete button also, it would make life so much easier rather than having to find the item in the box of spawned items which may be a lengthy list, plus, you might delete the wrong item there. :(
Also, maybe an 'Undo' button which undos things one at a time?
