When you open a script in Visual Studio through the Unity Editor, the Scripting API documentation is automatically opened. I suspect showing the browser tab and rendering the html inside adds about 1 or 2 seconds to the VS startup time. I always close that tab so it's just cluttering the tab bar for me. Is it possible to disable automatically opening the Scripting API documentation? There's no option for that in the "Tools for Unity" section. When "Use External Browser" is set to True it's still opened.
