Decorator add-in v1.0.0 was found guilty in disrupting Visual Studio operations, even causing a crash. It too often looked for a project associated with a window, particularly disrupting when the window was already closed.
I’ve added a dictionary to store a project for a tab. Now the project is searched in Visual Studio only once when the tab is created. You may also notice in source code how I use tab.TabItem for tab identity – this is because TabsStudioExt.Tab objects are created at will and only WPF controls and DTE objects are stable enough for identity purposes.
Download Decorator v1.0.1.

Hello Sergey,
You said that “You may also notice in source code how I use tab.TabItem…”.
Is there source code in my licenced tabsstudio?
Best Regards.

I meant Decorator’s source code that is included in the download archive along with the precompiled Decorator.dll.
