Usability: if i mouse-over a statement in Wikidata, either the property or the value, like the "instance of" or the value of it, there is a popup with the Qnnn or Property:Pnnn and a drop down menu. I think the Qnnn and Pnnn text in the popup should not be a link, because I can already click on the item itself (with the same result), so it's redundant. The biggest usage of that number is to copy it. Copying a link is much harder than copying regular text - I can double click the number to select it, whereas with the link, i have to be very careful to select right before the link text starts. Since I copy a lot of these values, it would be a great usability help.

Also, please remove the "Property:" prefix -- simply takes up a lot of room without much help, as it's meaning is obvious from the position of the value and from the letter P in front of the number.
