A control type that automatically acts as a search for a specific table. Rows of the table would be filtered by whether they matched the query, and columns in the matching rows would be highlighted if they matched (even specific strings in columns could be highlighted).
This is currently more or less achievable with the existing set of controls, using a dynamic filter on the table that runs against the contents of a text control. Conditional formatting can similarly be used to highlight some columns. See demo doc:
However it is a bit cumbersome to have to manually create this control, the filters, and conditional formatting each time. It would be nice to just plop down a built-in search control, point it to a table, and then have that table automatically controlled by the search control. This could even offer some nice features as options like fuzzy matching, ignoring case, expanding note previews, only matching text-fields, etc…
