Yes, I think this would be a good idea. Just note that Hype works by storing copies of files internally, and only keeps a loose link to the original. A 'reveal in finder' would be to this original, which might have lost linkage at some point for a variety of reasons (copying to a different machine is the common culprit). If you want to edit files in Hype's control, instead you can use the "Edit" menu in the resources library. It will likely corrupt your document if you open the files directly within the .hype document while open.
