Thanks; this is useful. I feel like a dill, but I followed these instructions and for some strange reason the package does not appear in the list after I have loaded it. The console tells me that the package has been loaded successfully, but it simply doesn't appear in the list, even after I have refreshed the list. Any thoughts? Cheers, Andrew

Thanks alot!!!

Man, I keep ending up at your channel. Keep up the great work!
