Imagine that the items would have the command/snippet/macro symbol in front of them to make it clear what was what.
I guess it could be hidden. When I use something, I don't care about it being a macro or a snippet or jack. I think it just adds a superfluous layer of complexity -- but that's just my idea.
And much like the go to symbol window, if more than one item has the same name, it would append the bundle name at the end to make them unique.
...while I'd like this to be the default ;)
