Hi;
Adding a button called "Comparing (diff only)" like the current "Comparing selected revisions" (see [1]) it would be useful and faster for history checkers. The button must link to &diffonly=1 comparison. This avoid loading (and rendering?) the whole page, what is slow for large pages.
Regards,
