Auto-pin an extension when on a website

I have so many extensions it’s hard to find the one I want from the menu. So when I am on a website like youtube, then I want to auto-pin all the Youtube related extensions to the toolbar . Then unpin when I navigate off Youtube. Allow me to set certain criteria for each site. Same example when I’m on Wikipedia, only pin the Wikipedia related extensions. If I am on a shopping website, then pin the related extensions. But some extensions I want to be pined all the time, regardless of current site.
