As far as I can tell at this point, there is no way to be able to count the number resources I have available. I find this important because, over the years I have lost a few books. Usually it's because of a problem with a file. One needed only to delete the file and reload it from the FTP site to restore the resource. Now there appears to be no way to keep track of what we have unless you go looking for a specific resource and can't find it. Not very satisfactory when you have thousands of resources.
Another feature I don't see is the locked titles. Granted a lot of people don't keep these in their library but some of us do - after all, you can easily find the contents of the locked resource and see if it might meet a current need.
As to the interface, I'm afraid I don't share the enthusiasm of many - I find the thing drab and colourless, made worse by the fact that there are no defining margins so that the whole thing becomes one amorphous blob. Might as well have a black and white monitor for this.
I still haven't had much of chance to look at the functionality, and it's still indexing my library 24 hours later. It has also bogged down my computer to a crawl, but I expect this is a temporary phenomenon (hopefully).
