Having a Popover - component that handles positioning, portals, click-outside, focus trapping, and transitions (see how in 5 Things I Learned Building My Own Popover) - unlocks a solid foundation for building more complex UI components on top of it.

A unified procedure for managing SSH keys across multiple GitHub and GitLab accounts - (almost) entirely from the terminal, with no private keys on disk. Works for both first-time setup and key rotation.
