Hi Salvatore

to use semi-transparent circles as vertex markers:

settings = QSettings()
settings.setValue("/qgis/digitizing/marker_style", "SemiTransparentCircle")

That code can be put somewhere in the application's initialization.
Other values are "Cross" and "None". You can also change the size of
the marker:

settigs.setValue("/qgis/digitizing/marker_size", 3)
