I am using Xubuntu 16.04.
I am wondering if there is a way to have multiple opened instances of the same application stack into a single tab like Windows does it.
Then when you clickthat tab, it is expanded into a small secondary menu display all of the instance.
Right-Click on your panel and select Panel > Panel Preferences.
Click on the Items tab and select Windows Buttons.
Click on the Gear on the right for Edit the currently selected item (my icon pack shows it as an eye ball). Change Window Grouping to Always.
Hope this helps!
