As per the topic, preview pane plugins. What I mean by this is create a plugin system to allow other developers to create plugins which can be used to preview files in the preview pane.
For example, right now the media preview is limited to the windows media player interface and file types that windows media player supports. With plugin support this would be interchangeable so that another media player could be used and could support other file types.
Another example could be syntax highlighting. Right now if I select a .cpp file, it's a text file so it gets displayed as normal text, but a plugin could perform syntax highlighting.
in a way, the image previewer is already open since people can write their image extractor shell extensions for custom file formats and x2 will pick them
the media player and text viewer though are monolithic

And therein lies a good reason to make this sort of thing into plugins. I never use the media previewer, yet it is still loaded when browsing my music and videos. If this were a plugin I could remove it and x2 would then be lighter.
