Lightroom :: 4 - How To View RAW And JPG Files

I know there is the option to "treat jpg as seperate files" in the library, but i feel it clutters up the library so i tend to avoid this. However, if i treat them as the same, the JPG does get saved into the hard-drives directories, but it isn't visible at all in LR. I understand that this is by design, but what is the point of it then, if there is no way for me to look at the jpg (e.g. for comparison).
 
so my question: is there a way to see the jpg file, unless i treat it as a seperate file (and hence de facto duplicate the number of images in my library)? what i am looking for, is occasionally being able to view that jpg that has been saved to the directory.
