Tabs Studio Blog (organizing Visual Studio document tabs)

1. Change tool tip show delay for the whole tab and extensions to 500 ms (default delay is 1500 ms):

<Style TargetType="TabsStudio:Tab" BasedOn="{StaticResource DefaultTabStyle}">
    <Setter Property="ToolTipService.InitialShowDelay" Value="500"/>
</Style>
<Style TargetType="TabsStudio:TabExtension" BasedOn="{StaticResource DefaultTabExtensionStyle}">
    <Setter Property="ToolTipService.InitialShowDelay" Value="500"/>
</Style>

2. Add XP like top orange adornment for the selected tab:

<Style TargetType="TabsStudio:Tab" BasedOn="{StaticResource DefaultTabStyle}">
    <Style.Triggers>
        <Trigger Property="IsTabSelected" Value="True">
            <Setter Property="Background">
              <Setter.Value>
                <LinearGradientBrush StartPoint="0,0" EndPoint="0,1">
                    <GradientStop Color="Orange" Offset="0"/>
                    <GradientStop Color="White" Offset="0.2"/>
                </LinearGradientBrush>
              </Setter.Value>
            </Setter>
            <Setter Property="Margin" Value="0,-1,0,0"/>
        </Trigger>
    </Style.Triggers>
</Style>
