Please add "close all open inactive window button" similar to what Revit has. This will help a lot with efficiency.
There's one that's close already. Rt. Click on any tab > Close other Tabs.
What I would like to see though is something that Chrome has which is Close other Tabs to the Right.
Ctrl+Shift+W will close all, there is also a "close other tabs" when right clicking on a tab.
(Close other tabs can also be set to a keyboard shortcut)
