Tabs Studio Blog (organizing Visual Studio document tabs)

Below is the visual tree of Tabs Studio controls with base types and additional properties:

Tabs : TabPanel
|
 - Tab : TabItem (IsTabSelected, IsMultiExtensions)
   |
    - TabToolTip : ToolTip (IsTabSelected)
   |
    - TabInternals : DockPanel (IsTabSelected)
      |
       - TabNameGroup : StackPanel (IsTabSelected, IsMultiExtensions, IsNameReadOnly)
      |  |
      |   - TabName : Label  (IsTabSelected, IsMultiExtensions, IsNameReadOnly)
      |  |
      |   - TabNameReadOnlyImage : Image (IsTabSelected, IsMultiExtensions, IsNameReadOnly)
      |
       - TabExtensionGroup : StackPanel (IsTabSelected, IsExtensionActive, IsExtensionReadOnly)
      |  |
      |   - TabExtension : Label (IsTabSelected, IsExtensionActive, IsExtensionReadOnly)
      |  |  |
      |  |   - TabExtensionToolTip : ToolTip (IsTabSelected, IsExtensionActive, IsExtensionReadOnly) 
      |  |
      |   - TabExtensionReadOnlyImage : Image (IsTabSelected, IsExtensionActive, IsExtensionReadOnly)
      |
       - CloseTabButton : Image (IsTabSelected)

TabToolTip, TabInternals and CloseTabButton are missing IsMultiExtensions property – I’ll fix it in the next version. IsMultiExtensions is true when tab is a group of 2 or more extensions.
