This looks awesome! It's to a large part like a modern shell environment I try to imagine since some time. Maybe it needs more data-flow spread-sheet features,

This looks awesome! It's to a large part like a modern shell environment I try to imagine since some time. Maybe it needs more data-flow spread-sheet features, need to check it out, but the screenshots strongly point into the right direction. Funny coincidence that it's build in Pharo which I've mentioned here in another comment. :-)
