How can the main window title in Squeak and Pharo be set?
In Pharo I thought it could be set in the System -> Settings Menu but couldn't find anything there.
Can it be set only in code?
Try this in Squeak:
HostWindowProxy basicNew primitiveWindowTitle: 1 string: 'My Title' squeakToUtf8
In Etoys we have a convenience method for this:
DisplayScreen hostWindowTitle: 'My Title'
(because Etoys shows the current project name as window title)
