Three columns, one job
Navigation, filtering and records each get their own column, so narrowing a list never hides the list. The filter rail separates three quick filters from seventeen detail filters, which keeps the common cases at the top and the long tail collapsible.
A table that says where you are
Selected rows stay tinted rather than only ticked, the toolbar shows the active filter and sort as removable chips, and the footer states the record count next to the pager. Between them, the screen answers what you are looking at, how it was narrowed and how much more there is.
A command bar instead of a floating widget
The assistant sits in a full-width bar at the bottom edge with its keyboard shortcut written into the placeholder, so it is reachable from any screen without floating over the data.
