// on the right; Favourites and Recent (from the store, so they work
// before anything loads) are one list each.
//
// Like a pane, it's either browsing (letters: j/k, [ and ] for tabs, f
// star, / to type) or typing a filter (ctrl+ letters). esc while typing
// clears the text and goes back to browsing; esc while browsing closes.
// F opens it on Favourites and R on Recent, browsing; search on Search,
// typing, on All. search again narrows to the source you were in, and
// back to All.

// The results don't move by themselves: as lists load, rows already shown
// keep their order and new ones come after them, with the cursor on the
// same entry. Starring keeps an entry where it is, its ★ showing the
// change. Only typing or picking another tab or scope re-sorts them.
