Is it true that all toolbars are always visible when using the Short Message Viewer?

The correct answer indicates that irrelevant toolbars are hidden automatically when using the Short Message Viewer. This functionality allows the viewer to provide a cleaner and more focused interface by not displaying toolbars that are not useful at a given moment. The automatic hiding of toolbars helps to enhance user experience by minimizing clutter and ensuring that users can concentrate on the primary content without distractions from non-essential tools.

This design is typical in software applications where context-sensitive toolbars improve usability. In contrast, the other statements suggest that all tools are always visible, that users can manually adjust visibility, or that customization options allow for all toolbars to remain visible. While customization may be a feature in many applications, the core functionality highlighted here revolves around the automatic management of toolbar visibility based on relevance.
