1) make the give-focus-to-TB a toggle, giving focus to the current view if the TB already has the focus. 2) Ensure that the TB loses the focus when it is hidden. 3) use coloring to mark the focused item in the TB, taking into consideration dark mode. The colors come from gui2.library.models. I don't really care what color is used. 4) Disable using the platform edit keys to edit TB items. Those keys don't permit asking the question about whether virtual libraries should be respected. This leaves using the context menu to start editing, which is how it has been forever. 5) Keep the focus on the TB when one uses RETURN to toggle the item. While there, ensure that RETURN is valid only if the TB is allowed to have focus.
