Yes. You'll note that in the Connectors flap there are Maker Buttons 
(though they probably don't look like them) with labels. The logic in 
NCMakerButton for receiving a dropped Morph can generate a label 
(which is the name of the Morph, so name the Morph from the halo 
first). However, it only does this if the buttons are labeled, and 
the only time this happens currently is if they're in a NCPartsBin 
(like in the Connectors flap).

So you could make a subclass of NCMakerButton that answers true to 
isLabeled (or just change isLabeled). And use these buttons instead 
(easiest if you also subclass NCButtonBar and change its 
buttonClass).

You have to find the labels.
This is cleverly hidden in a method called "labels" <g>.
Then : "aLabel contents" gives you their text; "aLabel string: 
'newString'" changes their contents.

Yeah, probably, though it's in a .pr project. I suppose I could post 
it separately on SqueakMap.
