First, expore the new morph, and name the morph, such as:
self name: 'NameString'
Then, when you need to find the morph later use #externalName, roughly like
what Jecel suggests:
| stopButton |
stopButton := nil.
self allMorphsDo: [ :m | (m externalName = 'NameString') ifTrue: [
stopButton := m ] ].
stopButton ifNotNilDo: [ :b | b ... ].
In my code, I store all of the submorphs I want in local variables for
(note that I use #allMorphsDo: - this check morphs embedded in other morphs
in your main morph, which I did a lot of!).
