I don't really care what they look like but if there is a way to exend this area with a plugin or completely remove it from the layout, the one posting how to do it will get a beer/coffee in Cambridge this summer.

Ah, that’s easy. There is only one sender of buildTextAreaButtonsColumn: so, if you do { sourceCodePanel. "self buildTextAreaButtonsColumn: aWindow"} reverse do: [:each | sourceCodeContainer addMorph: each]. in NautilusUI>addAll: instead of { sourceCodePanel. self buildTextAreaButtonsColumn: aWindow} reverse do: [:each | sourceCodeContainer addMorph: each]. they are gone. Putting them into a plugin is left as an exercise for the reader. Stephan
