There are still a number of functions that are not accessible (as far as I know) from the command box. Yet having them accessible in that way would give us users more power.
For instance, if I could access "Show Notes and Highlights" from the command bar, I could make it a button on the toolbar and use it to toggle that function easily. Other such options could be used in a similar way by those who so desire (e.g., "Show Bible text only").
If this is feasible and not too difficult to implement, it would be quite convenient.
