In some IDEs, there's an option to snap/scroll the left hand pane (files/projects etc) to the relevant item when you change tabs on the right hand side.

In the Studio3T context, this would mean:
- You change tabs (with the new setting / preference on)
- The connections pane highlights and scrolls to the collection / server for the newly selected tab

This would be useful, for example if you have multiple servers open, with multiple connections in each.
