This is a minor thing that I don't even need I just run into it after trying out some styles I found online, and though you might want to look at it.

In windows it seems like if you have this:
<Style x:Key="{x:Type ComboBox}" TargetType="{x:Type ComboBox}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ComboBox}">
<Grid>
<Grid.Resources>
<Style TargetType="ToggleButton" x:Name="comboToggleStyle"> or <Style TargetType="{x:Type ToggleButton"} x:Name="comboToggleStyle">
</Grid.Resources>
......
<ToggleButton>
.......
All Toggle buttons within that Grid in the template will apply the comboToggleStyle instead of the global one in windows but in NoesisGUI I get my normal style.

I tried this on a combo box style in Unity but I assume that this is the case for all usages of <Grid.Resources> with a type style like that in NoesisGUI, but that is only a guess. I'm not even sure if I like that construction but you probably aim to get as close as normal windows behavior as possible in NoesisGUI.
