Tabs Studio Blog (organizing Visual Studio document tabs)

TrackEd add-in shows a yellow or green bar in the tab title for modified and saved documents:

You can customize these colors first by applying the following Tabs style (copied from TrackEd source):

<Style TargetType="TabsStudio:TabNameModificationMarker" BasedOn="{StaticResource DefaultTabNameModificationMarkerStyle}">
<Setter Property="Template">
  <Setter.Value>
    <ControlTemplate TargetType="{x:Type TabsStudio:TabNameModificationMarker}">
      <TextBlock Name="TabNameModificationMarkerTextBlock" Padding="0" Margin="3,2,0,2"  Text=" "/>
      <ControlTemplate.Triggers>
        <DataTrigger Binding="{Binding Path=(TabsStudioTrackEd:Properties.DocStatus),
                 RelativeSource={RelativeSource AncestorType=TabsStudio:TabNameGroup}}" Value="Dirty">
          <Setter TargetName="TabNameModificationMarkerTextBlock" Property="TextBlock.Background" Value="#E5AC00"/>
          <Setter Property="Visibility" Value="Visible"/>
        </DataTrigger>
        <DataTrigger Binding="{Binding Path=(TabsStudioTrackEd:Properties.DocStatus),
                 RelativeSource={RelativeSource AncestorType=TabsStudio:TabNameGroup}}" Value="Saved">
          <Setter TargetName="TabNameModificationMarkerTextBlock" Property="TextBlock.Background" Value="#009900"/>
          <Setter Property="Visibility" Value="Visible"/>
        </DataTrigger>
      </ControlTemplate.Triggers>
    </ControlTemplate>
  </Setter.Value>
</Setter>
</Style>

<Style TargetType="TabsStudio:TabExtensionModificationMarker" BasedOn="{StaticResource DefaultTabExtensionModificationMarkerStyle}">
<Setter Property="Template">
  <Setter.Value>
    <ControlTemplate TargetType="{x:Type TabsStudio:TabExtensionModificationMarker}">
      <TextBlock Name="TabExtensionModificationMarkerTextBlock" Padding="0" Margin="0,2,0,2"  Text=" "/>
      <ControlTemplate.Triggers>
        <DataTrigger Binding="{Binding Path=(TabsStudioTrackEd:Properties.DocStatus),
                 RelativeSource={RelativeSource AncestorType=TabsStudio:TabExtensionGroup}}" Value="Dirty">
          <Setter TargetName="TabExtensionModificationMarkerTextBlock" Property="TextBlock.Background" Value="#E5AC00"/>
          <Setter Property="Visibility" Value="Visible"/>
        </DataTrigger>
        <DataTrigger Binding="{Binding Path=(TabsStudioTrackEd:Properties.DocStatus),
                 RelativeSource={RelativeSource AncestorType=TabsStudio:TabExtensionGroup}}" Value="Saved">
          <Setter TargetName="TabExtensionModificationMarkerTextBlock" Property="TextBlock.Background" Value="#009900"/>
          <Setter Property="Visibility" Value="Visible"/>
        </DataTrigger>
      </ControlTemplate.Triggers>
    </ControlTemplate>
  </Setter.Value>
</Setter>
</Style>

And then change colors for the name and extension to your values. For example, after changing default #E5AC00 Dirty color to #D90000 it looks like this:
