//! The visibility query bar.
//!
//! Always visible, always the raw query. Anything that filters the list, a saved view
//! today, a filter builder later, writes into this string rather than replacing it with a
//! structure you cannot see or edit. That the web UI hides the query behind a filter widget
//! is the single most irritating thing about using it.
