I use NS2 for live performance. It would be a massive help to be able to be able to make shortcuts to projects in folders. That way set lists could be built inside individual folders, with the shortcuts opening the original project. A workaround is to copy the project into a folder, but this of course uses up more storage space on the iPad. A shortcut would use less than 1k of space (just as many bytes as the path requires, plus potentially the block size for files on the iOS filesystem). It would also mean that changes to the original project file would be reflected in all of the set list folders.
