Problem: In the Date selection popup, e.g. on the User contributions page after "To date:", if clicking Up Up (^ then ^), the list of years is the current and next decades (2020 to 2039). The next decade is unlikely to be required.
Proposed solution: Please change the range of years displayed to the previous and current decades.
Who would benefit: Users looking for contributions at dates earlier than 2020.
More comments: This would only save one click for each search, but it's an easy enhancement of usability. It would increase the number of times that users would enter dates by point-and-click rather than typing the date in full.
