Currently it appears column customization (sort order, filter, column width) is only preserved between executions for the first tab and only when it is the active tab then the queries are run. Would be nice if it was preserved for all tabs.

In one query window:

SELECT Data= 1 UNION SELECT 2 UNION SELECT 3;

SELECT Data= 'A' UNION SELECT 'B' UNION SELECT 'C';

Run the query and the results are put on to results at tabs. If you change sort orders for the second tab and re-run the sort order is lost. If you change the sort order of the first tab and rerun with that tab still the active one the sort order is preserved.
