This navigation control offers Outlook 2003, Office 2007, and Office 2010 style options, with flexibility for hosting controls within panels. It also features automatic adaption to the XP color theme, the ability to collapse and expand controls, and define logical sections within panels.

This component provides extensive control over the appearance of the software, making it VCL and VCL.NET compatible. Its flexible structure allows hosting controls inside the panels, providing greater design flexibility. The component also offers the capability to define logical sections within the panels, which enhances the software design by providing a clear separation of sections.
The feature that stood out for me is the automatic XP color theme adaption, which is optional. This feature automatically adapts the color palette of the software to the XP color scheme. Additionally, the component provides an option to collapse/expand the control, which adds to its usability.
If you are looking for a powerful software component that provides an extensive range of design control to your software's interface, this TMS Component Pack is undoubtedly worth considering. It offers all the above features and more. So, make sure to give it a try!
