Current behavior: Pasting http://example.com results in literally http://example.com added to the file. Markdown automatically displays it as a link, but without title information.
Desired behavior: Allow URLs to be pasted/dragged into the form of [Page Title](http://example.com), according to the page’s HTML <title> tag. This is also how a browser saves bookmarks.
This could use an alternate shortcut such as Ctrl/Cmd + Shift + V, sharing the same mode as Ability to paste with behavior like Word's "Merge Formatting".
