I love it, just nodes and shortcuts, like Nuke.
Although I do wish you could have a floating viewer like Nuke, and just press a shortcut to hide or show it.
hi niel,
im also a long time XSI user
you can right click on a sop node and choose preview window. that will open as psuedo 3d view of your object in chain.
you can also map the parameters option to a hotkey so you have a floating window just like xsi.
i also made a python for opening and closing nuke paramter window so i feel at home.
best of luck
