When searching within a view, add a toggle to display only matching records / hide non-matching records
How does it solve user problems?
Quickly surface matching records within a view to see results "at a glance" instead of jumping to each match. Prevents having to click "next" button repeatedly if there are multiple search term matches within a single record.
It's different from setting a filter within a view, because each filter rule only applies to a single field.
Who is the target audience?
Interestingly, the mechanism already exists in Airtable, but only in the Calendar and Timeline views. Click the "See records" button, and type in a search term in the sidebar that appears. You will see a filtered list of records, and it searches all fields. It's a feature I use everyday, but I've never seen it mentioned anywhere.
