I'm considering switching back to Rhino v6 or v5 from v7. Though v7 is amazing it grinds my gears that the Copy-Paste functionality between MoI and Rhino is broken. Michael, do we have a change of making this function working again? It's really a bumper in my workflow (of course you can always have different versions of Rhino installed at the same time, but still).
