not currently and not easily. the Enhancer window doesn't use Winamp's skinned frames (seeing as it predates that support by a few years) which would automatically allow it to snap or dock to the other windows when using Bento or any of the other other modern skin windows.
it was enough of a challenge to try to make it work with all of the classic skin windows as part of the wrapper plug-in i created to fix issues with using it on newer versions of Windows and Winamp (http://www.nunzioweb.com/daz/enhancer/
) and there's no simple way that i'm aware off to be able to get it working with modern skins.
i might be wrong but i couldn't find anything obvious when i did the classic skin support - though i've just had a thought in that maybe embedding the window into a skinned frame might work but as i've recently halted plug-in development, other than noting this down there's not much chance of me ever getting around to trying to implementing it to see if it would be viable.
