Just that I can highlight text (like those annoying links) and when I move to a new location like in a browser it is 50/50 whether anything will actually be on the clipboard and transfer to the new location.
I shouldn't have to do anything extra when working with URLs and IP addresses, they should just be entered by default as plain text with no link. I document a lot of stuff that we don't want links ... we just want to document the FQDN or IP of something.
