When more than one photo is selected, and more than one copy name is passed, I mean, in Windows anyway, maybe Mac too.
First off, I realize the SDK v5 has not been released, so if this bug report is premature, just ignore it.
That said, I wanted to report ASAP in the hopes that it will be fixed before SDK 5 is released, if applicable.
Problem is, plugin has no official way of assuring Lr is in grid mode. So createVirtualCopies needs to be fixed, or we need a way to force grid view, or both.
Again, my apologies in advance: I acknowledge this is an undocumented function.
