Comment 1 for bug 1023540

Thanks for reporting. This is indeed not configurable was just forgotten.

However, this will probably be "fixed" in a different way as the "Recently used" menu is removed in the next version (0.3.2) and is replaced by a bookmarking functionality for files and pages. I am uncomfortable with the current implementation since there is no way to disable it whereas storing bookmarks on disk must be disabled/enabled in the settings, hence the switch to explicitly bookmark files. (Of course, there will still be the recently used functionality in the GTK file dialog which is probably where it belongs anyway.)
