I'd like to see an advanced view in recent changes (instead of or in addition to the current line view). It could include things such as the card name, a link to show the card in change view, who made the change, when the change was made and an edit summary.
You could still be able to view the card on advanced view recent changes. If you click the card name the hidden card could slide down under its line. Clicking the link to show the change could slide down the card in change view.
