Advanced site control with horizontal, vertical or tabs dock zones, splitters and shifting "auto hide" zones.

Transparent hot-spots drag-over active areas.

Additional drag-over active areas in tab zones and splitters.

Ability to place required user interface controls on the panels (TLMDDockPanel) - prevents having many distinct forms in the project.

Advanced design-time features with drag-and-drop zones rearrangement.

True proportional zones resizing. The LMD-DockingPack uses double coefficients to store proportional sizes that prevent proportion-lost bug while very slow resizing.

The notion of "space" zone. That is the central zone with main application content. The central zone has following useful special properties: space zone have highest priority to resize when the dock site is resizing, leaving all other edge zones with the same size; edge zones "auto hide" side is automatically detected relatively to space zone.

Using space zone gives following additional features: Unlike Delphi standard sites, like TPanel, dock-client can be docked into empty site to the edge, not only to the whole site area. This is more naturally from the user viewpoint. Dock-out of the space panel from the site does not corrupt edge zones layout.

Built-in native tabbed documents support: including special hotspot areas, close tab buttons and special floating form style.    

Allowing locking some panels to prevent them to be dock-out from the site, using DragMode, ShowHeader and Buttons properties of the TLMDDockPanel.

Allowing intercepting dock-dropping using OnCustomInsertQuery and OnCustomInsert events of the TLMDDockSite. These two features allow organizing fully custom central zone, like "tabbed documents" in Microsoft Visual Studio.

Advanced global saving/loading of the current dock layout. The TLMDDockManager control allows to save/load any all dock sites, including dynamically created floating sites, in XML format. TLMDDockSite.LoadDesignLayout property and TLMDDockManager.ApplyDesignLayout method allows to defer applying design-time layout in application to prevent flickering.

Advanced dock panel lifetime management with OnCloseQuery, OnClose events and Release method.
