When editing a link, you can only edit the link's title, not it's URL.
This means I can't go back and remove irrelevant URL query parameters (like utm_source and the like).
It also means I can't copy the URL to a video and just change the timestamp where I want it to start replaying.
And that latter is something I (want to) do quite often when I'm working through a highly quotable TED talk for example.
Please enable editing the URL as well as the title of links.
