Currently when you click on "Show only selected rows", the tool just adjusts column heights. Ideally this tool would have option or by default, apply a FILTER to the column. This would allow you to select the rows in the spreadsheet. Currently if you try just to select and copy the highlighted rows Excel selects the ENTIRE column (all rows) for a cut-and-paste. If a Filter was applied the cut-and-paste would only operate on the selected rows.
