crash one to crash all like on Mac? What advantage does that bring?

Worksession in Rhino for Windows allows opening multiple files in one window, but only one file can be modified. Switching to modify another file can take a bit of time. Worksession | Rhino 3-D modeling (mcneel.com)

My understanding is Worksession cannot be implement in Rhino for Mac.

This topic was discussed in depth back in 2001. It’s called “Multiple Document Interface” or MDI. At least that’s what it was called back then. I came from a CadKey background which had MDI, and I thought I would need it in Rhino too. Turns out just opening multiple Rhino’s was just as useful, and as Gjis alluded too, a crash doesn’t bring everything down.
