It would be very useful to add to the list of cached items that is automatically generated.
For example, I may have images, or javascript libraries elsewhere that I’d like to be loaded in the cache, but don’t want to duplicate the files in my hype project directory.
If we could add to the manifest as we do with the HEAD document, leaving what’s automatically added (uneditable and in gray) but leave a space to add lines for more images/files, then we wouldn’t have to hand edit the cache.manifest every time we export.
