In one of these fora where a sample is posted, it would be nice to just open the URL, or more specifically import a local copy.
This would be useful in both the cloud version and the local version.
Of course in the cloud version , it would not strictly need to be within SM, but could be a third button on the launcher page after "upload file"

This does beg whether SM needs a bundle-export (like Lyx) that zips all files required by the current document.
