Wow very cool improvement indeed :-) Thank you so much for these fixes and style improvements 🥇

When testing, I've seen that the Light VS 2013 Theme looks a little broken now, would you be able to fix this please?

There are Surpresse Message in Chinese in DockingManager.cs - Can you please translate these into English? I have tried Google Translate but does not really output much useful English :-(

There is a AvalonDockIcon.design file in the repository. Is this left there by mistake or on purpose? What program would I need to open it?

AvalonDockIcon.design is a file of icons,open it by Microsoft Expression Design 4

@Dirkster99

I don't have Microsoft Expression Design and there is not Community Edition (?). Can we use a file format that is also available in Microsoft Expression Blen (Community)?

this file just can be opened by that soft，Its a great soft for wpf，we can design
Path gemetry or transfer an AI to that, you can search expression studio try to get it, or tomorrow I send a url to you

Its OK if you can send me the url later :-) I found in the meantime that we broke a feature in the last pull request

• I saw it only now by testing with TestApp:
  The SetWindowSizeWhenOpened Feature is broken #174

The feature was implemented with this pull request:
#146

Microsoft Expression Studio 4 Ultimate is not support，I just have a chinese version,should I send a email of it to your?

these Figures are created by Microsoft Expression Studio 4 Ultimate,Microsoft Expression Design is one part of this sln

Hi LyonJack,

I found a bug in the styling that bothered me quit a bit and is only visible in Ähnlich and Edi - I am not sure why the issue is not visible in MLibTest :-(.

The issue is that the ContextMenu looks broken and the ToolTip is no longer usable:

嗨LyonJack，
我在样式中发现了一个困扰我退出的错误，并且仅在Ähnlich和Edi中可见-我不确定为什么该问题在MLibTest中不可见:-(。
问题是ContextMenu看起来坏了，ToolTip不再可用：

For now I have resolved these issues by removing the additional ToolTip and ContextMenu styles from the Generic.xaml file as shown in the linked commits and everything looks OK as shown below.

I just wonder if you need these styles and if so if there is a better solution?

Thanks Dirk

现在，我已经通过从Generic.xaml文件中删除其他ToolTip和ContextMenu样式（如链接提交中所示）解决了这些问题，如下所示，一切看起来都不错。
我只是想知道您是否需要这些样式，是否需要更好的解决方案？
谢谢德克

Here is a test application to verify the issue and resolution:
