Definitely a lot of great ideas in here, keep on posting stuff!

Just a note - I think that probably the initial focus for this will need to be for handling a larger quantity of items.

I'd definitely like to have an optional way for it to be used in a smaller panel, there are many options for this like a pop-up or entry on the bottom toolbar as shown above, also another idea is to have it as an item on a tab on the side pane similar to "Construct", "Transform", etc...

But I think that lightweight option will have to come later, once a more comprehensive mechanism is available first.
