I really like the ribbons in AutoCAD, it beats all the toolbars I use to have cluttering my screen. One of the problems I constantly run into is I have to switch panels to access things like changing the layer.
So I have a quick tip for you! Add things you use frequently to the “Quick Access Toolbar”! To do this, simply right click on the Layer control or whatever you want and chose “Add to Quick Access Toolbar. Now that feature is accessible no matter which Ribbon Tab you have current.
