Most 3D software is absolutely vast. These programmes provide a great number of tools, options and customisation, but that can make for a steep learning curve. With that in mind, the developers often create quick-access menus, which can be hugely beneficial, especially for tasks you do less frequently, where the mental muscle memory hasn’t been solidly created yet.
Maxon has added a few of these to Cinema 4D and, although they are great for quickly finding a nested command, they also serve to allow users to create more working room for their viewports and managers. You could conceivably have an interface set up that has no buttons at all, and simply rely on keyboard shortcuts and a couple of really useful and powerful pop-up menus to navigate almost everything the software has to offer.
