Did that lose your existing tree structure and flatten everything?

Nope. I did the following steps: (1) uninstall TST (2) restart browser (3) install TST (4) restart browser.

All the tabs were as is. But I also purposefully did not open or close any tabs between (2) and (3). Not sure what the impact of that would be.
