The functionality to export a toolbar is not apparent.
Please refer below discussion thread for your information,
I just recreated the Toolbar segment, which is oddly, Pascal’s Dropline : )
And then I moved all the rest of what I use to the main toolbar.
The toolbar/workspace system is as clear as mud.
Perhaps if there some kind of diagram how what there is-is supposed to work.
That said, the actual button-bars and tabs are work and look very good.
