First of all big thanks to @Retro808 for this startup screen. It is just missing a little thing for my taste.
For ISOs which are in .zip or .rar I like to have a progression bar showing how the loading is going.
If you are interested
add :
<Grid Grid.Row="3" Grid.Column="2" Grid.ColumnSpan="3">
<Grid.RowDefinitions>
<RowDefinition Height="80*" />
<RowDefinition Height="5*" />
<RowDefinition Height="15*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="{Binding LoadingWidth}" />
<ColumnDefinition Width="{Binding LoadingEmptyWidth}" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Row="0" Grid.RowSpan="2" Grid.Column="0" Grid.ColumnSpan="2" Text="{Binding NowLoadingText}" Foreground="#26CAF7"
HorizontalAlignment="Center" VerticalAlignment="Center" FontSize="30" FontStyle="Italic" FontWeight="Bold" Typography.Capitals="AllSmallCaps" />
<Grid Grid.Row="1" Background="#26CAF7" />
</Grid>
at the bottom of the .xaml, just before
</Grid>
</Canvas>
</UserControl>
