When you close History the sidebar is closed.

Is there a setting to prevent this:
When you open History (Ctrl-H), and then close it, the sidebar is closed.

I would like TST to re-open automatically and not have to click up on the TST button.

I don't think you can get around that behavior as that is how Firefox handles Ctrl-H followed by another Ctrl-H. However, you could do Ctrl-H to bring up history and then "F1" to bring up TST.

He is right. TST is just a sidebar panel and there is no way to go back to TST's sidebar panel after other panels are closed. It is the only way: switching to TST directly from History sidebar.

Thank you, save my life.
