hi everyone, i got some clarification from the development team on the TSV / XLS issue. You can still open the report in a spreadsheet format if you follow these instructions:
In the report, click the Download TSV option. Save the file to your Desktop or some other location on your computer. Go to the file, right-click on it, point to Open With, and then select Choose Program. In the dialog, click Select the program from a list, and then click OK. Select Microsoft Office Excel (or other spreadsheet program). To always open TSV files with that program, be sure to select the Always use the selected program to open this kind of file option. The next time you download a TSV file, you can double-click it to open.
