I'd throw in restructuring the Supreme Court. Lifetime appointments seem to have devolved into them being wildly politically swingy based on when very-old people decide to retire (or die), with a strong incentive to then install the youngest doctrinaire ideologues you can get through the Senate. (And to engage in political brinksmanship to push an appointment back a few months to give it to the other party if you can, etc.) Give them a fixed number of years and have new ones appointed on a schedule that's synced to presidential terms.
