Hello Rick,

Hope you are feeling well now.

Regarding your requirement, the TabStrip widget does not provide a way for adding custom action buttons and you could add only additional tabs to it and try to use them for your custom logic, but please note that you will have to prevent the selection of those additional tabs if you need to only execute some custom logic.

For your convenience, following is a dojo example demonstrating how to add additional tabs dynamically and how to prevent the selection:
