Visual Studio 2015 'New Window'/Multiple Instances for HTML files

Question

Visual Studio 2015 has the "New Window" button and "Window|New Window" menu item disabled for HTML files. I need this feature enabled.

I've found ways to do it for VS 2010, but not for VS 2015. Any suggestions?

Answer 1

It work fine in VS2017 community edition.

You can try to create custom toolbar and add it as button from Window/New Window
