Add XAML Editor configuration persistance in Visual Studio

[YannikBartel]

I like to alter the XAML Editor (designer) default appearance configuration in Visual Studio. Slider position, zoom-level (etc.).
Basic solution: add it to Visual Studio Options. (As its already done for document view).
Advanced solution: persist last used options automatically (for each file individually).

hm is this the right repository? Or VS extension? Can you give me a quick hint?..
