Extension:PrefStats

PrefStats extension collects and displays statistics for when users have started/ended using certain options. The extension adds a special page, Special:PrefStats, that shows a chart and some statistics about tracked preferences.

It was developed specifically to be run as part of the Beta rollout on Wikimedia wikis; it may or may not be useful to third-party users. The extension can of course be run on non-WMF wikis, but documentation is still very limited.
