The default setting in visual studio Show pinned tabs in separate row is disabled.
You can see the Class4.cs and Class2.cs are pinned, and in a row mix with unpinned files(Class1.cs and Class3.cs). Now if you’re like me who wants to work in a separate row for all the pinned files. Go to Tools -> Options -> Environment -> Tabs and Windows -> Show pinned tabs in separate row and enable the show pinned tabs in separate row.
Once you’re done both Class4.cs and Class2.cs will be in a
different row since both are pinned files.
When working in Visual Studio I pinned files that I want to have
a more focus. Try it, you might like it.
