I have a suggestion for a change to the OG Tracker spreadsheet which should add value to the course.

Reference the problem numbers using three full digits every time.

Example: Instead of listing DS-Q1 and DS-Q14, list them as DS-Q001 and DS-Q014.

The reason for this is that it will make the spreadsheet sort correctly. Currently, sorting ranks DS-Q103 < DS-Q3 because evaluates strings using alphabetical rules rather than numeric ones.

This change would be quick and easy to make and would significantly improve the task of cutting and pasting Problemlist.xls results into the tracker.

Hope that helps.
