Steps to reproduce the problem:
1. Open multiple windows of a single application, e.g. multiple Chrome browser windows.
2. Note how there is only one icon for the application on the shelf.  There is no way to directly choose a window from the shelf.

The workaround is to click on it, which opens a window which is probably not the one I want, thus changing Alt+Tab order which interrupts my workflow for switching windows in that manner.  Then I have to click on the icon again, and finally with a third click I can select a particular window.

I find this clumsy and inefficient.  I realize some users must like this, as Chrome OS is not the only window manager I've seen do this in recent years, but there should be an option for disabling it.

What is the expected behavior?
I expect an option to not group windows in the shelf/taskbar, so that I can easily switch to specific windows.

What went wrong?
1) It takes 3 clicks to pick a window, instead of 1.

2) The first click opens a window which, if it's not the one I want, changes Alt+Tab ordering in a non-intuitive way because it injects a window which I did not want to open into the beginning of the recently-used-based order.

3) I cannot see the list of windows without two clicks or Alt+Tab keypress.

Did this work before? No
