Before I put a proposal onto the village pump, I wanted to make sure it's even possible:
Can Special:PrefStats be activated for all Gadgets (the JS gadgets that can be enabled in Special:Pref). This would make it easier for JS devs to track the number of times a gadget is used, as well as estimate possible impacts of code changes.
Version: unspecified
Severity: enhancement
