Shorten the SharePoint URLs
SharePoint URLs are particularly very long and annoying. It isn't convenient to email to someone or store the URLs somewhere. I know people who don't like to use SharePoint just because of the long URLs.
Not only shorten but also mask using something like tinyurl. The current link reveals all sorts of information that opens security holes if shared externally.
Additionally, allow link defaults to be set and retained so that things like setting external links to not allow editing can be done once and only changed when needed. This has to be done manually for every shared file currently.
