Visually organize tags toolbar

As our tags list grow larger, I think it’s great if we can visually organize and group together tags in the top toolbar, to make it easier to navigate.

I know Make it possible to use a hierarchy to organize tags - #12 by zdeno exists

But I’m proposing a simpler solution, where we can just move it around akin to the bookmark toolbar in our browser and add an " | " to separate and group tags
I think this is a more intuitive solution and easier to implement
