Hi Michael,

I would never put toolbars on a second monitor, because I find the mouse traveling too long that way.
That's why I also prefer to use shortcut for functions, or contextual pop over menu.

MoI has the less intrusive UI compared to any other software I use, on a 2560*1440 monitor, the 3D view is very huge and pleasant to use.

So as a personal preference, I would eventually like to have an other 3D viewport on the second monitor (that's the way I work in Modo), but with couple of options, that might be tricky to implement.

For instance Modo had tons of options by viewport.

- different shading mode (wire, reflection, smooth shade)
- different shading/visibility based on active/inactive layers : very handy to get an isolate element on the 'working' viewport, and whole scene on the other screen.

But that only reflects my way of working.
