Point 1: Yes even I think so that we should have an ability to move the tabs. You can share your idea on idea exchange forum
Point 2: Good one but could you please explain what benefits will it bring to the table i.e., to have their own tabs rather than going back to their respective commands. Modules need to reference General Lists and/or LISS hence the need to open them side by side so that it becomes easy for model builders to point and click.
