My tabbar is full and cannot find a way to make it wider or a double tabbar.
How can I extend it?
So, it is not possible?
Nope, not really. Too many plugins. There was a toolbar layout editor in GH for Rhino5, but it was terribly bad. I think I have a much better idea, but it hasn’t been added yet, and may in fact never be added to GH1 since it is quite a significant amount of typing.
