Thanks Dave, I'm glad you like it.

Are you asking about the outer frame UI, like the bottom toolbar and side pane? For that MoI uses my own custom UI library that is built on top of the IE HTML renderer (mshtml.dll).

The UI is defined by .htm files, which you can see in the \ui subdirectory under MoI's main program files directory. If you look through those you will see a bunch of custom elements for many things like <moi:CommandButton>, <moi:TabButton>, etc...

There are some cool features to this UI mechanism - like for instance you can scale the entire UI up or down to your preference by using the UI size: slider in the Options dialog.
