Hello Alex,

Would it not be good to put classic pharo scrollbars (as was the case with Mondrian, see the attached screenshot from a mondrian visualization) for Roassal visualizations?

regards,
Usman

Hi Usman,

I have been slow on this. Thanks for pushing!
I will try to come with an implementation for next Sunday.

Cheers,
Alexandre
