"I think your asking how to create a new Measurement toolbar that you can dock separately? See the screenshots..."
Not exactly. In Version 15 under "Options" and "Toolbars and Menu", when you select the "Measurement" toolbar, it opens without a tab. In later versions, selecting the same "Measurement" option opens it with a tab. When I then drag the "Measurement" toolbar up to the top of the Window to "dock" it along with "Snap", "Boolean and Facet", etc, "Measiurement" stays "tabbed", and the line-width expands to accomodate it. I want to turn off the tab But if I select "Measurement" under the "Toolbars" menu, the "Manage Tabs" option is grayed out and inactive.
